If $$tan^{2} θ = 1 - e^{2}$$ , then the value of $$secθ + tan^{3} θ cosecθ$$ is
we know , 1 + $$tan^2 \theta$$ = $$sec^2 \theta$$
given that $$tan^{2} θ = 1 - e^{2}$$
$$sec^2 \ theta$$ - 1 = 1- $$e^2$$
$$sec^2 \theta$$ = 2- $$e^2$$...........(1)
Now , $$secθ + tan^{3} θ cosecθ$$ = $$sec \theta + tan^{2} \theta tan \theta cosec \theta$$
= $$sec \theta(1+ tan^2 \theta)$$ = $$sec^3 \theta$$................(2)
Using equation 1 and 2
$$secθ + tan^{3} θ cosecθ$$ = $$(2-e^2)^\frac{3}{2}$$
