Simplify: Sin2x/1-Cos2x

Prove: sin2x / 1 - cos2x = cotx My Attempt: LS: = 2sinxcosx / - 1 - (1 - 2sin^2x) = 2sinxco...

Sin2x/1-Cos2x

what does sin2x/cos2x equal to?

d2y/dx2+9y=cos2x+sin2x

Prove that sin2x+cos2x-1/sin2x+cos2x+1=tanx

sin2x − cos2x − tan2x = 2sin2x − 2sin4x − 1/...

if a=cos2x + sin2x and b=cos2y + isin2y.then find (a + b)

Simplify. cos2x+sin2x+cot2x csc2x sin2x 1 cos2x cot2x
