Q1: Given the following pairs of values of x and y. X 0.7 0.8 0.9 1.0 1.1 1.2 1.3 y 0.644218 0.717356 0.783327 0.841471 0.891207 0.932039 0.963558 Use Forward difference approximation to numerically determine the first, second and third derivatives at x = 1. Q2: Use forward, backward and central difference approximations to estimate the first derivative of f(x)=e²x +1 at x=2 using a step size h=0.2. Compare the results with the exact values.
