    L. H. S

    = 1 + Tan0

    Tan0 1 – 1

    1 – tan0 tan0

    = 1 + Tansq0

    Tan0(1 – tan0) tan0 – 1

    = 1 + Tansq0

    Tan0(tan0 – 1 ) tan0 – 1

    = Tansq0 1

    (tan0-1) Tan0(Tan0 – 1)

    = Tancube 1

    Tan0(tan0 – 1)

    = (tan0 – 1) (tansq0 + 1 +tan)

    Tan0 (tan0 – 1)

    = Tansq + Tan0 +1

    Tan0

    = Tansq + Tan0 + 1

    Tan0 Tan0 Tan0

    = Tan0 + 1 + cot0

    = Tan0 + cot0 +1
