Okay well, I looked through my calculus notes and textbook and I can't find what to do when you are integrating a function of the type a/u where a is a constant and u is some linear function of x. I know that the integral of 1/x is ln(x) but what about when you have something like(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int \fract{3}{100+2t} [/tex] which is 3/2 ln(100+2t).

If I recall the derivative of ln(u) is u'/u, so I assume it must somehow be like that. I am sure I learned how to integrate it somewhere along the road... must've been asleep that class or something though...
