Question #5584

Calculate numerically the following integral with Matlab:

integral(0 t0 4)(e^x/sqrt(1+x^2))dx

use the rectangular quadrature of the following form:

I=integral(a to b)f(x)dx=(b-a)f(a)

using this quadrature, derive a compostive quadrature rule and the formula to compute this integral.

Write a Matlab function computing this integral.
