C) Evaluating a more complex function. To demonstrate the power of determining derivatives numerically, let's apply the same technique to three rather complex functions. It would be a challenge to develop an analytical expression for the derivative of the three functions below, but, numerically, it should not be too difficult. Please write the code to estimate the derivative of each of the following functions as described below. e sin(x) 1. Estimate derivative of f(x) = at x = 1. e (2) 2. Estimate derivative of f(x) = = at x = 0.1 3. Estimate derivative of f(x) = cos(x)In() at x = 2
