Tutorial Exercise Find the derivative of the function. y = sin 1(5x + 1) Step 1 The function y = sin (5x + 1) is a composition, and so we must use the Chain Rule, given below, to find the derivative. d dx [f(g(x))] = f '(g(x))g'(x) For the given function sin (5x + 1), the "inside" function is 5x + 1 and the "outside" function is f ( x ) = X Submit Skip (you cannot come back)
