Quad function: Evaluate integral Problem

Hello, I am trying to evaluate this integral I attached. I made the function and I put the code in the editor to run it. But for some reason I keep getting an error with the function I made. The error is at my expression that I made for some reason. Please help.

Thank you

You need to do element-wise exponentiation (as well as division, that you already included) in the evaluation of ‘myfunb’:

y = sin(x)./sqrt(1-4*sin(x).^2);
