There is an equation like y=cosx. I want to integrate this equation from 0 to pi. However, I should use the trapezoidal rule to find integral. There are 5,7,...,43 points(h) that are equally spaced. For each number of points(h) I should find the Integral. For instance h=5, I=? this process should be repeated for all h values from 5 to 43. regards,

doc trapz % seems to cause confusion?
