Homework Statement Evaluate ∫(1/x)sin^2(x)dx from -a to a The Attempt at a Solution Mathematica doesn't want to evaluate this because of the lack of convergence. I think it is zero. When we consider non-zero values of x in the associated riemann sum, the integrand is odd and so...

A more simple example might serve to make this clear: consider a train that is accelerating with acceleration a. You are on this train and you drop a ball. The only force due to a physical interaction acting on the ball is that of gravity which is due to the ball's interaction with the Earth...
