I also doubt that Mupad or Maple will try experimenting with a polar coordinate change that could simplify the inner integral. What have you got against numerical methods, Marcio?

I have abso-bloody-lutely nothing against numerial integration. In actuality, I love numerical methods, of course, that does not mean I am an expert. I am just a junior engineer who loves maths and eventually find it interesting to play with calculus on rainy weekends.

Alright... my question is... how do I solve the inner integral numerically if the upper limit is not a number but an expression? I tried with the substitutions you proposed it pushed me to the drawing board, meaning it hit some point that neither mupad nor maple could go any further.

Thank you
