Relations and functions
Eight marks. Types of relations and the inverse trigonometric functions, which look like a short unit and quietly decide how comfortable the rest of calculus feels, since derivatives and integrals keep returning to them.
Topics Covered
- Reflexive, symmetric and transitive relations
- Equivalence relations
- One-to-one and onto functions
- Inverse trigonometric functions: domain and range
- Principal value branch
- Graphs of inverse trigonometric functions
