Hello, I have a tricky integral to show positivity of. Here are the knowns: f is piecewise linear continuous, f' <= abs{2}, H(s) = 0
between -1 and 1, and s[ln(s)+- sqrt{s^2 -1}] +- sqrt{s^2 -1} otherwise.
I wish to show that int [f'(s)H(s)]ds outside interval [-1,1] is positive. One suggestion is to show that the integral
is = int [f(s) [ln(s) +- sqrt{s^2-1}]] but I am unable to do this.
Any discussion is appreciated. I am an algebra grad student. This is needed for evaluation of other integrals and I am stuck. Thank you
