Studying for my math final, and I'm having some problems with some integration questions... the first:
Integrate (bottom limit of 2, upper limit of 4) (3/x)dx
this doesn't look hard, and apparently the answer is 3ln2 but I have no idea how to get there.
The second is:
Integrate (bottom limit 1, upper limit 2) [dt/(8-3t)]
And the answer is (1/3)ln(5/2)
anyone wanna give me a hand with this?
