Homework Statement
Look at the figure below. Derive the formula for the magnitude of the force F exerted on the large block (mC) in the figure such that the mass mA does not move relative to mC. Ignore all friction. Assume mB does not make contact with mC.

The title contains the problem I have difficulty with.
I understand I must use u substitution and then integrate by parts.
So my actual problem is: How do I find the derivative of arcsin(x^2) if u = arcsin(x^2)?
I know the derivative of arcsin(x^2) is 1/(1-x^2)^1/2
Thanks for...
