Multiply and simplify: (1+tan(θ))(1+tan(θ))-sec(θ)tan(θ)
on simplifying we get 2.
We are given an expression (1+tan(θ))(1+tan(θ))-sec(θ)tan(θ)
We get,
(1+tan(θ))(1+tan(θ))-sec(θ)tan(θ)=1+2tan(θ)+tan2(θ)-sec2(θ)tan(θ)=sec2(θ)+2tan(θ)-sec2(θ)tan(θ)=2tan(θ)tan(θ)=2
On simplifying we get the expression as 2.
Establish each identity.
1+cosθ+sinθ1+cosθ-sinθ=secθ+tanθ
sin3θ+cos3θsinθ+cosθ=1-sinθcosθ
find the exact value of the expression
