  1. Step-by-step explanation:

    sinθ(1+tanθ)+cosθ(1+cotθ)

    =sinθ+

    cosθ

    sin

    2

    θ

    +cosθ+

    sinθ

    cos

    2

    θ

    =sinθ+

    sinθ

    cos

    2

    θ

    +

    cosθ

    sin

    2

    θ

    +cosθ

    A=

    sinθ

    sin

    2

    θ+cos

    2

    θ

    +

    cosθ

    sin

    2

    θ+cos

    2

    θ

    As,sin

    2

    θ+cos

    2

    θ=1

    A=

    sinθ

    1

    +

    cosθ

    1

    = cosecθ+secθ
