I have posted a link there to this thread so the OP can see my work.Calculus integral problems. Please help I would appreciate.?

1. Consider f(x)= 1/x on [1,3]. Use four sub-intervals to approximate the integral from 1 to 3 f(x)dx by using the Midpoint Rule.

2. Suppose f(x) is a continuous even function and that the integral from 0 to 6 f(x)dx=96 and the integral from 0 to -2 f(x)dx =10. Find the integral from -2 to -6 f(x)dx.
