Every time I try to do a simple definite integral simbolically such as:(adsbygoogle = window.adsbygoogle || []).push({});

Integrate[R/P - c1/(T^2), {P,P1,P2}]

it takes about 2 minutes then gives a long conditional expression. Basically it assumes that P1 and P2 are general numbers with complex parts and negative and such.

HOW do I tell mathematica that these are just simple real numbers >0? I looked around at using assumptions but after 2 months I still cannot figure it out and it's VERY frustrating.

Thanks
