Question

Prove: cotx/(cscx-sinx)=secx

Answer 1

this question was already answered right?

Answer 2

I don't know.

Answer 3

I asked the same question twice :(

Answer 4

anyway...cotx/(cscx - sinx) = sinx

left hand side:

cosx/sinx/(1/sinx - sinx)

cosx/sinx/(1 - sin^2x)/sinx

cancel sinx

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

1/cosx = secx
secx = secx

Answer 5

None of these explanations are clear to me but if you understand, that's all that matters.
