Homework Statement
How would you prove:
sin4x/ 1-cos4x * (1-cos2x/cos2x) = tanx
It was our Thinking and Inquiry question on our test today and I didn't know how to prove it.
The Attempt at a Solution
I'm not sure if I was headed in the right direction but this is what I did:
LS:
2(2sinxcosx)/ 1-2(1-2sin^x) * (1-(1-2sin^2x)) / cos 2x
And then I expanded from there.
What I tried to do was to change everything to that it was SIN on top and COS on bottom to get TAN, but I didn't know how to continue.
