Question 785176: prove sinA tanA = (cotA cscA)/(cotA cscA)

This is NOT an identity because the right side has 
the same numerator and denominator and therefore
the right side equals to 1.

Therefore 

sinA tanA = 1

This has solutions approximately 51.8° and 308.2°.

So it is not an identity.

The problem is botched.  You may post the correct
identity in the thank-you note and I'll help you.
