यदि `2tan beta + cot beta =tan alpha ` सिद्ध कीजिए की
` " " cot beta =2tan (alpha -beta ) `

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

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

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

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

if 2tan beta+cot beta=tan alpha then prove that cot beta=2tan(alpha-beta)

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

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

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

If tan alpha - tan beta =m and cot alpha - cot beta =n , then prove that cot ( alpha - beta )= (1)/(m)- (1)/(n)

(no alpha + no beta) / (no alpha-no beta) = (tan ((alpha + beta) / (2))) / (tan ((alpha-beta) / (2)))
