Study Notes
Trigonometric Integrals and Substitutions
- Trigonometric integrals involve integrals with trigonometric functions and integrals that can be transformed into trigonometric integrals by substitution.
One-to-One Functions
- If f is one-to-one, f(7) = 3, and f'(7) = 8, then f^(-1)(3) and (f^(-1))'(3) can be found.
Inverse Functions
