I had a question about the problems sets at the end of part B, and in particular, the ones concerning chain rule and inverse trig functions. For 5A-3g, I'm finding it hard understanding how they got the answer in the solutions. I am pretty rusty when it comes to working with radicals, and I'm stuck with the problem. it says: Differentiate with respect to X: arctan(x/sqrt(1-x^2)). I would appreciate any guidance with this, thank you for looking!
