Question

What should I do to integrate this?
\[\int \frac{4}{3+cosx} dx\]

Answer 1

Step 1: Multiply top and bottom by conjugate of the bottom

Answer 2

what techniques you got at your disposal?

Answer 3

It will look juicy to us with a bottom with one term :)

Answer 4

Got it. So, would it be similar if I change 1 on the top to 4 and 1 in the bottom to 3?

Answer 5

lol freckles juicy :P

Answer 6

Perhaps I shall rewrite the question first.

Answer 7

Latex fails :S
This one:
\[\int \frac{4}{3+cosx} dx\]

Answer 8

is that the question now?

Answer 9

So this is a new problem you are saying?
And yes you do multiply the conjugate of bottom on both top and bottom

Answer 10

but pull out the constant first so it's not confusing :P

Answer 11

i see this wont be as juicy as before...

Answer 12

\[4\int \frac{3-cosx}{9-cos^2x} dx\]
Not something nice to me :(

Answer 13

wait one sec

Answer 14

Actually, this is the question I wanted to ask. But... start with an easy one first is pretty good.
