Prove that : tan θ/(1 − cot θ) + cot θ/(1 − tan θ) = 1 + sec θ cosec θ
In a right triangle ABC, right-angled at A, if sin B = 1/4, then the value of sec B is
sec A = 2 cos A is true for A =
(cot θ + tan θ) equals :
Prove that : √((sec A − 1)/(sec A + 1)) + √((sec A + 1)/(sec A − 1)) = 2 cosec A
Prove that : (1/cos A − cos A)(1/sin A − sin A) = 1/(tan A + cot A)
