Question
I need HELP Verify the identity
Cot3X/CSCX=cosX(csc2X-1)
Cot3X/CSCX=cosX(csc2X-1)

testing if x = 20º
LS = cot60/csc20
= sin20/tan60 = .1975
RS = cos20(1/sin40 - 1)
= .5222
Your equation is NOT an identity.
A check should always be your first step when proving complicated-looking trig "identities".
