Hello, I have been some days trying to solve this exercise, does anybody know how to do it?

I have to write a matlab routine that computes the integral $\displaystyle \int_{-1} ^{1} dx \frac { f(x) } { (1-x^2)^{1/2}} $ with the accuracy $\displaystyle 10^-8$ using the Gauss-Chebyshev quadrature and use it to compute the following integral

$\displaystyle \int_1^2 dx \frac { e^{2x} }{ ( (2-x) ( (1-x))^{1/2} } $

Thanks in advance
