Definite integrals, kinematics, optimisation and modelling explained with rigorous IB-style reasoning
What you'll learn
✓ Understand the concept of integration as the inverse process of differentiation and as accumulation of change.
✓ Evaluate indefinite and definite integrals using correct notation, limits, and fundamental integration techniques.
✓ Interpret definite integrals as area under a curve and apply integration to calculate areas between curves.
✓ Apply integration to kinematics problems involving displacement, velocity, acceleration, and initial conditions.
✓ Solve optimisation and modelling problems using integrals and differential equations in IB exam style.
✓ Justify results clearly and avoid common IB errors in integration, applications, and interpretation questions.
Requirements
● Core algebraic manipulation and function notation
● Core algebraic manipulation and function notation
● Interpretation of graphs and functions from IB Mathematics AA HL
● The content of Modules 1 and 2 of this course (foundations, limits, and differentiation)
● No prior knowledge of integration is required — the topic is developed from first principles
Description
This course is the third module of a structured IB Mathematics AA Higher Level series and focuses on one of the most demanding and conceptually important parts of the IB syllabus: integration and its applications.
In IB Mathematics, integration is not treated as a purely technical skill. Students are expected not only to compute integrals correctly, but also to interpret them, apply them in unfamiliar contexts, and justify conclusions using precise mathematical reasoning. Many students lose significant marks in this topic not because the calculations are difficult, but because the interpretation, structure, and modelling required by IB questions are not properly understood.
This module develops integration systematically, starting from foundational ideas and building toward full IB-level applications.
You will study
• Indefinite and definite integrals from first principles
• Integration of polynomial functions and substitution techniques
• Area under curves and area between curves
• Kinematics using integration (velocity, displacement, motion models)
• Optimisation problems using calculus
• Differential equations and modelling with real-world applications
• Full worked IB-style exam examples with detailed explanations
Every lesson is designed in strict alignment with the IB Mathematics AA HL syllabus and assessment criteria. The focus is not on memorising procedures, but on developing correct mathematical thinking, interpretation of results, and clear written justification — exactly as required in IB examinations.
The module includes structured lectures, guided examples, targeted exercises with full solutions, IB-style tests, and a final exam to consolidate understanding.
This course is ideal as
• Core preparation for IB Mathematics AA HL calculus topics
• Support alongside school teaching
• Revision for internal assessments and final IB examinations
• A foundation for advanced applications in later modules
By the end of this module, you will not only know how to integrate — you will understand how and why integration is used, and how to apply it confidently in IB-level problems.
This course is intended for purchase by adults (parents, guardians, teachers, or adult learners).
Students under the age of 18 may only access this course through an account created and managed by a parent or legal guardian, in accordance with Udemy's policies.
Who this course is for
■ Parents or guardians supporting students preparing for IB Mathematics AA Higher Level
■ IB Mathematics teachers and tutors looking for structured exam-aligned material
■ Adult learners preparing independently for the IB Mathematics AA HL syllabus
■ Schools and educators seeking high-quality calculus instruction aligned with IB standards
