One of the best things about IB Mathematics? You don't have to memorise every formula!

Whether you're studying IB Mathematics: Analysis and Approaches (AA) or Applications and Interpretation (AI), you'll have access to an official IB Mathematics Formula Booklet during your exams.

But there's a catch: having the formulas doesn't automatically mean knowing how to use them. You'll still need to understand which formula applies, what each symbol means, and how to use it to solve unfamiliar problems.

In this guide, we'll walk you through everything you need to know about the IB Math Formula Booklet, including where to find it, what's included for SL and HL students, and how to make the most of it to maximise your marks.

What Is the IB Mathematics Formula Booklet?

The IB Mathematics Formula Booklet is an official resource provided by the International Baccalaureate (IB) containing mathematical formulas students may need throughout their Diploma Programme mathematics course.

Rather than memorising every equation, students can refer to the booklet during their exams to find formulas for topics such as algebra, geometry, statistics, probability and calculus.

There are two main versions of the booklet, corresponding to the two IB Mathematics subjects:

  • Mathematics: Analysis and Approaches (AA): Focuses on mathematical reasoning, algebra, functions, calculus and analytical problem-solving.
  • Mathematics: Applications and Interpretation (AI): Focuses on mathematical modelling, statistics, practical applications and the use of technology.

Both subjects are available at Standard Level (SL) and Higher Level (HL). Each subject has its own formula booklet, with separate SL and additional HL content.

⭐️ Important: The formula booklet is a reference tool, not a replacement for understanding the mathematics. The IB still expects you to recognise the appropriate method, apply formulas correctly and explain your reasoning.

Our tip: Download or print the correct formula booklet at the beginning of your course. Keep it beside you when completing homework, topic questions and practice exams so you become familiar with its layout long before your final assessments.

What's Included in the IB Math Formula Booklet?

The formula booklets cover the major mathematical topics studied in IB Mathematics. However, the exact formulas available depend on whether you're studying AA or AI, and SL or HL.

Let's break down the key sections and some examples of the formulas you'll encounter.

1. Number and Algebra

This section covers important formulas involving sequences, series and algebraic relationships.

For example, the sum of the first (n) terms of an arithmetic sequence is:

\[ S_n = \frac{n}{2}\left(2u_1 + (n-1)d\right) \]

Where:

  • \(S_n\) = Sum of the first \(n\) terms
  • \(u_1\) = First term
  • \(d\) = Common difference
  • \(n\) = Number of terms

Example: An arithmetic sequence starts at 5 and increases by 3 each term. Find the sum of its first 10 terms.

Substituting into the formula:

\[ S_{10} = \frac{10}{2}\left(2(5)+9(3)\right) \]
\[ S_{10} = 5(37) = 185 \]

Exam tip: Before choosing a formula, identify whether the sequence is arithmetic (constant difference) or geometric (constant ratio). Confusing these two is an easy way to lose marks.

2. Functions

Functions are an important part of both IB Math AA and AI, particularly when working with graphs, transformations and mathematical models.

The booklet includes relevant relationships and formulas for functions, depending on the course and level.

For example, the quadratic formula is:

\[ S_{10} = \frac{10}{2}\left(2(5)+9(3)\right) \]
\[ S_{10} = 5(37) = 185 \]

Example: Solve \(2x^2 - 5x - 3 = 0\).

Here, \(a = 2\), \(b = -5\), and \(c = -3\).

\[ x = \frac{5 \pm \sqrt{25+24}}{4} \]
\[ x = \frac{5 \pm 7}{4} \]

Therefore:

\[ \boxed{x = 3 \text{ or } x = -0.5} \]

Exam tip: The booklet won't tell you when a problem requires factoring, the quadratic formula or a graphical approach. You still need to recognise the most efficient method.

3. Geometry and Trigonometry

Geometry and trigonometry formulas are particularly useful for questions involving triangles, angles, distances and areas.

One important formula is the sine rule:

\[ \frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C} \]

Another is the cosine rule:

\[ c^2 = a^2 + b^2 - 2ab\cos C \]

Example: A triangle has sides of 5 cm and 7 cm with an included angle of \(60^\circ\). Find the third side.

Using the cosine rule:

\[ c^2 = 5^2 + 7^2 - 2(5)(7)\cos 60^\circ \]
\[ c^2 = 39 \]
\[ \boxed{c = \sqrt{39} \approx 6.24\text{ cm}} \]

Exam tip: Draw and label a diagram before using trigonometry formulas. This makes it much easier to identify the correct sides and angles.

4. Statistics and Probability

Statistics and probability are particularly important in IB Math AI, although both subjects cover relevant statistical concepts.

Depending on your course, the booklet provides formulas for statistical measures, probability distributions and related calculations.

For example, the variance of a binomial distribution is:

\[ \operatorname{Var}(X) = np(1-p) \]

Where:

  • \(n\) = Number of independent trials
  • \(p\) = Probability of success on each trial

Example: A basketball player has a 70% chance of scoring a free throw. If they attempt 20 independent free throws, find the variance in the number scored.

\[ \operatorname{Var}(X) = 20(0.7)(0.3) \]
\[ \boxed{\operatorname{Var}(X) = 4.2} \]

Exam tip: Before applying a probability formula, check whether the assumptions of the distribution are satisfied. For a binomial distribution, this includes a fixed number of independent trials and a constant probability of success.

5. Calculus

Calculus is especially important in IB Math AA, although it is also included in AI.

The formula booklet provides selected differentiation and integration formulas, with additional content for HL students.

For example, a standard differentiation rule is:

\[ \frac{d}{dx}(x^n) = nx^{n-1} \]

Example: Differentiate:

\[ f(x) = 3x^4 - 2x^2 + 5 \]

Applying the power rule:

\[ \boxed{f'(x) = 12x^3 - 4x} \]

However, simply knowing the differentiation rules isn't enough. You'll also need to understand how derivatives relate to gradients, stationary points, rates of change and optimisation.

Exam tip: Practise identifying when to differentiate or integrate before looking at the formula booklet. In more challenging questions, recognising the mathematical technique is often harder than performing the calculation.

What About Higher Level Formulas?

Higher Level students study additional mathematical content and therefore have access to extra formulas.

For example, depending on the subject, HL content can include more advanced calculus, complex numbers, vectors, probability distributions and differential equations.

If you're studying HL, make sure you're comfortable navigating both the SL and HL sections of your booklet. Don't limit your revision to the additional HL pages!

IB Math AA vs AI: What's the Difference?

Although both courses use formula booklets, the way you'll use them can be quite different.

Feature IB Math AA IB Math AI
Main focus Algebra, mathematical reasoning and calculus Modelling, statistics and real-world applications
Typical questions Analytical and algebraic problem-solving Contextual and technology-supported problems
Formula booklet use Supporting algebraic and analytical methods Supporting modelling, statistical and applied methods
Calculator use Paper 1 without a calculator; Paper 2 with a calculator Calculator required for all examination papers
HL assessment Additional Paper 3 Additional Paper 3

Which booklet should you study?

If you're taking IB Math AA, prioritise understanding algebraic techniques, functions, trigonometry and calculus. For IB Math AI, pay particular attention to statistical methods, modelling and interpreting results in context.

Regardless of your course, the most important skill is knowing why and when to use a formula, rather than simply finding it on the page.

How to Use the Formula Booklet in IB Maths Exams

Knowing your way around the formula booklet can save valuable time during an exam.

Here's a simple approach to using it effectively.

Step 1: Identify what the question is asking

Before opening the booklet, underline the important information in the question.

Are you finding a probability, solving an equation, calculating an area or determining a rate of change?

Identifying the topic first will help narrow down which formula you need.

Step 2: Locate the relevant formula

Turn to the appropriate topic section of your booklet.

For example, if a question asks for the sum of a geometric series, go straight to Number and Algebra rather than searching through every page.

Step 3: Check what each symbol represents

One of the most common mistakes students make is substituting values into the wrong variables.

Before calculating, identify what each symbol means and check that the given information matches the formula.

Step 4: Substitute and show your working

Write down the formula, substitute your values and show the key calculation steps.

This is particularly important because IB Mathematics markschemes award marks for mathematical methods and reasoning, not just final answers.

Step 5: Check whether your answer makes sense

Does your answer have the correct units? Is a negative length or probability greater than one reasonable? Have you rounded appropriately?

Checking your answer can help catch simple errors before you move on.

Common Mistakes Students Make With the IB Math Formula Booklet

Even with access to the correct formulas, students can lose marks through avoidable mistakes.

1. Relying on the booklet instead of understanding the mathematics

The booklet provides formulas, but it doesn't explain every method or tell you which equation to choose.

How to avoid it: Focus on understanding the purpose of each formula and practise recognising the situations where it applies.

2. Assuming every formula is included

Not every mathematical fact, algebraic technique or procedure is written explicitly in the booklet.

How to avoid it: Review your syllabus and identify the essential skills and relationships you must know independently.

3. Using the wrong formula

For example, students may confuse arithmetic and geometric series formulas or use the sine rule when the cosine rule is more appropriate.

How to avoid it: Learn the conditions under which each formula applies, not just what it looks like.

4. Spending too long searching for formulas

If you only open the booklet during your final revision, finding the right section can take longer than necessary.

How to avoid it: Use the booklet consistently throughout the course and during timed practice papers.

5. Forgetting to show working

Writing only the final answer can cost valuable method marks, particularly if your answer is incorrect.

How to avoid it: Write out your formula, substitution and key steps clearly, even when using a calculator.

Five Tips to Succeed in IB Mathematics

1. Familiarise yourself with the booklet early

Don't wait until exam season to learn what's inside.

Spend time browsing the sections and identifying where important formulas are located. The more familiar the booklet becomes, the less time you'll waste searching during exams.

2. Practise questions with the booklet beside you

When completing topic questions and past papers, use the formula booklet as you would in an actual exam.

Over time, you'll begin recognising formulas and their applications naturally.

3. Understand the formulas, don't just memorise them

Rather than trying to memorise every equation, ask yourself:

  • What does this formula calculate?
  • When should I use it?
  • What does each variable represent?
  • What assumptions or restrictions apply?

Understanding these questions is far more useful than memorising symbols without context.

4. Practise under timed exam conditions

Once you're confident with individual topics, move on to timed past papers.

Use only the resources permitted for your particular paper, including the correct formula booklet and calculator where allowed.

This will help you develop the speed and confidence needed for your final exams.

5. Review your mistakes and target weak areas

After completing a practice paper, don't just look at your final mark.

Review where you lost marks. Was it because you chose the wrong formula, misunderstood the question, made an algebraic error or struggled to interpret the result?

Keep a record of recurring mistakes and revisit those topics during revision.
