Question

integral(sin^5(x)/(1+cos^2(x))dx super confused :(

Answer 1

I don't even know how to begin starting this...
\[\int\limits(\sin^5(x)/(1+\cos^2(x))dx\]

Answer 2

im sorry, this ones' a little too difficult for me. sorry.

Answer 3

I'm in Calculus II DX

Answer 4

\[\int\limits(\frac{ (1-\cos^2(x))(1-\cos^2(x))(1-\cos^2(x) )}{ 1+\cos^2(x) }dx\]

Am i doing this right....

Answer 5

im sorry, im not sure, im taking calculus next semester. :(

Answer 6

it needs to be done by substitution method...

Answer 7

separate sin^5x into sin^4x * sinx
and then suppose u=cosx do derivative then you get du=sinx dx after that it might be easy....all the trig function will go away...
