Problem 47583. Approximation of an integral - Riemann sum

Riemann sum is a certain kind of approximation of an integral by a finite sum.
In this problem, I want you to use Midpoint Riemann sum to integrate a function.
As a test case, we should know that the integral of cos(x) over the interval [0,pi/2] is 1. Code numerical code, has only known spacing of the interval:
dx = pi/10;
x=0:dx:pi/2;
fx = cos(x([1:end-1])+dx/2)
riemannInt(fx,deltax)
ans =
1.004124203953987
Round the answer according to the test suite
