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.
