Consider the integration of the function f(x) = 1 + e-x sin(4x), over [a, b] - [0,1]. use exactly five function evaluations and compare the results from the composite trapezoidal rule and composite simpson's rule. take uniform step size h = 0.25. 2. let f(x)= cos(x), where x is measured in radians. use the central-difference formula of order o(h2) to calculate an approximation to f (0.8). compare your answer with the actual derivate of cos(x) at x-0.8.
