I'm doing code for the trapezoidal rule. I checked my code with simple functions at first to make sure it was outputting correctly. However when I am attempting what I need to do, my output says it's infinity, when it should not be. The solution I got from Wolfram Alpha and my TI89 was 0.00958. Could it be the "1/n" in the x definition? I needed 10 steps for the trapezoids I'm setting up.
The function being applied is: cos^2((pi*cos(x))/2)*csc(x).
n = 10;
x = 0:1/n:1/2;
