Warm-Up: November 13, 2012 • Find dy/dx
Derivatives of Inverse Trigonometric Functions Section 3.8
Derivatives of Inverse Functions • To find an inverse, we switch x and y • (a, f(a)) (f(a), a)
Derivatives of Inverse Functions • If f is differentiable at every point of an interval and df/dx is never zero on the interval, then f has an inverse and f -1 is differentiable at every point.
