verify following trigonometric identities. 1/sec0tan0 = csc0 = sin0

Trig 
Reiny,
check your typing, your statement is not true.

Trig 
Reiny,
I figured you must mean
1/(secØtanØ)  cscØ =  sinØ
Proof:
LS = 1/((1/cosØ)(sinØ/cosØ))  1/sinØ
= cos^2 Ø/sinØ  1/sinØ
= (cos^ Ø  1)sinØ
=  sin^2 Ø/sinØ
= =sinØ
= RS
