Grade 11 math
Use functions, trigonometry, sequences, and statistics to describe more complex relationships. Focus on interpreting a model as well as carrying out its calculations.

Your study guide
What you will explore.
- Analyze functions, sequences, and trigonometric relationships
- Build and compare mathematical models
- Reason about probability and statistical evidence
Before you begin
Review algebraic manipulation, graphs, powers, and right-triangle trigonometry. Some topics need specific function knowledge; the lesson prerequisites identify it.
Review Grade 10How to study these lessons
State the domain, units, and assumptions before calculating. Sketch how you expect the relationship to behave, then compare the solution with that prediction.
Work at your own pace. Open a hint when you need it, then try again before revealing the complete explanation.
Grade labels are starting-point guides; school sequences vary. University lessons introduce selected topics and assume the prerequisites listed on each page.
Practice with a moving example
600 guided practice chapters for Grade 11.
Try a distinct question, open a hint, compare the worked solution, and explore its interactive animation. These scenario chapters give you more practice within this level’s topics.
