(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]\int[/tex]sinxcosx/sin^4x+cos^4x

2. Relevant equations

sin^2x=1/2-1/2cos(2x)

cos^2x=1/2+1/2cos(2x)

sinxcosx=1/2sin(2x)

3. The attempt at a solution

[tex]\int[/tex]1/2 sin(2x)/(1/2-1/2cos(2x))^2 + (1/2 + 1/2cos(2x))^2

[tex]\int[/tex]1/2 sin(2x)/1/2 + 1/2cos^2(2x)

...?

Am I on the right track?
