You can put this solution on YOUR website! Prove the following identities:
csc = 1/sin
sin = 1/csc
csc = 1 divided by 1/csc
csc = csc
========================
sec = 1/cosx
cosx = 1/secx
cosx = 1 divided 1/cosx
cosx = cosx
========================
cot= 1/tan
tan = 1/cot
cot = 1 divided by 1/tan
tan = tan
