Question

sin(2x)/sin^2x

Answer 1

Simplify I'm guessing?

Answer 2

yea

Answer 3

Well, you have to know the identity for sin2x here. Theidentity for that is just 2sinxcosx. Once you have that in your numerator you can simplify :3

Answer 4

you beat me.

Answer 5

cosx/sinx is either cot or tan. and sinx/cosx is the another one of cot or cos. it may be needed.

Answer 6

how do you simplify the sin^2x, do you make it 1-cos^2x

Answer 7

No need. Once you simplify sin(2x) you'll have this:

\[\frac{ 2\sin(x)\cos(x) }{ \sin ^{2}x }= \frac{ 2\cos(x) }{ \sin(x) } = 2\cot(x)\]
Thats all that is needed :3
