" (b) "sqrt(an alpha)=cot beta=a," find "(alpha+beta)

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

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

If tan alpha = 7/5, tan beta=5/7 " then find the values of " tan (alpha + beta) " and " cot (alpha - beta)

If a sin alpha = b sin beta " then show that ", b cot alpha + a cot beta = (a+b) "cot"(alpha+beta)/2

alpha + beta = 5 , alpha beta= 6 .find alpha - beta

If 2 tan beta+cot beta= tan alpha , prove that cot beta= 2 tan (alpha-beta) .
