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
