derivatives of inverse functions gift 2004 1. Let g ( x ) x 5 3 x 2, and let g 1 denote the inverse of g . Then g 1 2 is equal to: A) 1 83 2.
Derivatives of inverse function – PROBLEMS and SOLUTIONS ( (𝑥)) = 𝑥 ′( (𝑥)) ′(𝑥) = 1. ′(𝑥)= 1 ′( (𝑥)) The beauty of this formula is that we don’t need to actually determine (𝑥) to find the value of the derivative at a point. We simply use the reflection property of inverse function:
Inverse functions. Let f(x) be a function. Recall f 1(x) is the inverse function of f(x), meaning y = f 1(x) if and only if x = f(y): You can also think of f 1(x) as \undoing" f(x), i.e. f(f 1(x)) = x and f 1(f(x)) = x: For example, ln(x) is the inverse of ex, since y = ln(x) if and only if x = ey: So eln(x) = x and ln(ex) = x for x > 0.
Worksheet: Derivatives of Inverse Trig Functions March 19, 2004 1. Let f(x) = cos−1 x. (a) Prove that f0(x) = −√ 1 1−x2. (b) Use the formula for f0(x) to explain why f is a decreasing function on its entire domain, [−1,1]. (c) Find f00(x) and use it to determine the intervals on which f is concave up and concave down. 2. Find the ...
