  1. Step-by-step explanation:

    cos

    2

    θ(1+tan

    2

    θ)=1

    Take L.H.S

    cos

    2

    θ(1+tan

    2

    θ)

    cos

    2

    θ+cos

    2

    θ.tan

    2

    θ

    cos

    2

    θ+cos

    2

    θ.

    cos

    2

    θ

    sin

    2

    θ

    cos

    2

    θ+sin

    2

    θ

    =1

    =R.H.S.

    plz mark as brainliest
