Hey guys! I'm very sorry to bump/thread-jack, but I need some help and don't have enough posts allowed to make a thread.
I'm a long time creeper both here and at H3F, but never really post. just have a quick question about identites and what not.
Basically, I just need help solving two problems. The first:
Solve the equation: 1-sin2x=(root3)cosx
And the second, Prove this is an identity:
sinx+cosx/tan^2 -1= cos^2 / sinx-cosx
Thank you in advance for all the help!
