Step-by-step explanation:
=
(secθ+tanθ) 2+1
(secθ+tanθ) 2 −1
= sec 2
θ+tan 2
θ+2secθtanθ+1sec 2
θ+tan 2 θ+2secθtanθ−1
= sec 2
θ+(tan 2
θ+1)+2secθtanθ(sec 2
θ−1)+tan 2 θ+2secθtanθ
= sec 2 θ+sec 2
θ+2secθtanθtan 2
θ+tan 2 θ+2secθtanθ
= 2sec
2 θ+2secθtanθ
2tan
2 θ+2secθtanθ
= 2secθ(secθ+tanθ)
2tanθ(tanθ+secθ)
= 2secθ2tanθ
=tanθ×cosθ
= cosθsinθ ×cosθ=sinθ
