Question
Prove the following identity tan x cos x/sin x=1/sin x cos x
Answers
Reiny
tan x cos x/sin x=1/sin x cos x
or
tan x cos x/sin x=1/(sin x cos x) ?
For either case,
LS = tanx(cosx/sinx)
= tanx cotx
= 1
For any given x, RS ≠ 1
Your equation is NOT an identity, so it cannot be proven to be true.

Its tan x cos x/sin x=1/sin x cos x

yup, that's what you typed the first time.
And I pointed out to you that that is not an identity.
