Question

Verify the identity.

cot θ ∙ sec θ = csc θ

Answer 1

\(\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}\qquad sec(\theta)=\cfrac{1}{cos(\theta)}\qquad thus \qquad cot(\theta)\cdot sec(\theta)\implies ?\)

Answer 2

\(\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}\qquad sec(\theta)=\cfrac{1}{cos(\theta)}\qquad thus\\ \quad \\ cot(\theta)\cdot sec(\theta)\implies ?\)
