[(5ecx+tan alpha)*cos(beta+tan beta)(sec n+tan x)],[=tan alpha*tan beta*tan theta],[(sec alpha-tan alpha)(sec beta-tan beta)(sec r-tan x)],[=2]

If (sec alpha+tan alpha)(sec beta+tan beta)(sec gamma+tan gamma)=tan alpha tan beta tan gamma, then (sec alpha-tan alpha)(sec beta-tan beta)(sec gamma-tan gamma)=

If 2tan alpha=3tan beta then tan(alpha-beta)=

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.

(tan alpha + tan beta )/( tan (alpha + beta ))+(tan alpha - tan beta )/(tan (alpha - beta )) =

If tan (alpha- beta)= (sin 2 beta)/(5-cos 2 beta) , find tan alpha: tan beta .

If tan alpha=(1-cos beta)/(sin beta), then a )tan3 alpha=tan2 beta(b)tan2 alpha=tan beta(c)tan2 beta=tan alpha(d) none of these

Prove that (tan alpha+tan beta)/(cot alpha+cot beta)=tan alpha tan beta

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

If tan(alpha-beta)=(sin2 beta)/(3-cos2 beta) then (a) tan alpha=2tan beta(b)tan beta=2tan alpha(c)2tan alpha=3tan beta(d)3tan alpha=2tan beta

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