How to calculate the drivative of tan 1 (x/sqrt(1x^2))?
The solution says it set y = as sqrt(x1) and it gives dy/dx = 1/(2sqrt(x1)). How is that possible? (Problem 2 18.01, Integration Techniques PDF 5A  3g)

This is actually a pretty cool problem, but a tough one, even with the minimal explanation provided in the materials. A full explanation is too long to type here so I wrote it up separately and posted it as a PDF.

Try to use Method of Substitution here x=cos2A will work
