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

• Trig -

check your typing, your statement is not true.

• Trig -

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
