Question: Approximate series solutions for two divergent solutions

Hi I am trying to compute the series approximation for the difference between these two divergent integrals

M := int(cosh(p)^2/sqrt(cosh(p)^2 - (1 + x)^2*sinh(p)^2), p = 0 .. 1/2*ln(1/x));

N := int((1 + x)*sinh(p)^2/sqrt(cosh(p)^2 - (1 + x)^2*sinh(p)^2), p = 0 .. 1/2*ln(1/x))

 

where x,p are positive and x is approaching zero. I would like to get a series expansion of M-N, but I am not quite if this is possible.

 

Please Wait...
