Exercise B.4: Use the Trapezoidal method The purpose of this exercise is to test the program trapezoidal.py. a) Let = e4x dx Compute the integral using the program trapezoidal.py and, for a given n, let a(n) denote the result. Try to find, experimentally, how large you have to choose n in order for l - a(n) SE where 8 = 1/100. b) Recalculate with = 1/1000. c) Recalculate with = 1/10,000. d) Try to figure out, in general, how large n has to be such that j - a(n)
