(tan alpha+cosec beta)^(2)-(cot beta-sec alpha)^(2)=2tan alpha cot beta(cosec alpha+sec beta)

(tan alpha+cos ec beta)^(2)-(cot beta-sec alpha)^(2)=2tan alpha cot beta(cos ec alpha+sec beta)

Prove the following identity: (1+tan alpha tan beta)^(2)+(tan alpha)(tan alpha-tan beta)^(2)=sec^(2)alpha sec^(2)beta

tan alpha=cot beta=a, find (alpha+beta)

If tan 2alpha = cot 2beta , then sec(alpha + beta) =

Prove that: tan^(-1){(cos2 alpha sec2 beta+cos2 beta sec2 alpha)/(2)}=tan^(-1){tan^(2)(alpha+beta)tan^(2)(alpha-beta)}+tan

(sec alpha * sec beta + tan alpha tan beta )^(2)-( sec alpha * tan beta + tan alpha * sec beta )^(2) =

csc^(2)(alpha+beta)-sin^(2)(beta-alpha)+sin^(2)(2 alpha-beta)=cos^(2)(alpha-beta) where alpha,beta in(0,(pi)/(2)), then sin(alpha-beta) is equals

If (sec alpha-tan alpha)(sec beta-tan beta)(sec gamma-tan gamma) = (sec alpha+tan alpha)(sec beta+tan beta)(sec gamma+ tan gamma) then show that each side is equal to 1 or -1.
