Question

Prove that : √(1+sinθ/1-sinθ) + √(1-sinθ/1+sinθ) = 2sec θ

Answer 1

Answer:

An equation involving trigonometry ratios of an angle is called is called a trigonometric identity, if it is true for all values of the angles involved. For any acute angle θ, we have 3 identities. i) sin² θ + cos² θ = 1 ,ii) 1 + tan² θ = sec² θ , iii) cot² θ +1 = cosec² θ.
