If tan (alpha + beta) = a + b " and " tan ( alpha -beta) = a-b, "then show that, " a tan alpha - b tan beta = a^(2)-b^(2)

If tan (alpha+beta)=a+b and tan(alpha-beta)=a-b,thenshowtâtan alpha-b tan beta=a^(2)

If tan(alpha+beta)=a+b and tan(alpha-beta)=a-b then show that atanalpha-btanbeta=a^2-b^2

(sin(alpha+beta))/(sin(alpha-beta))=(a+b)/(a-b) then (tan alpha)/(tan beta)=

If cos alpha+ cos beta= a sin alpha+ sin beta=b , then show that "tan" (alpha)/(2)+"tan" (beta)/(2)= (4b)/(a^(2)+b^(2)+2a)

Let alpha,beta,gamma>0 and alpha+beta+gamma=(pi)/(2). Then prove that sqrt(tan alpha tan beta)+sqrt(tan beta tan gamma)+sqrt(tan alpha tan gamma)<=sqrt(3)

If sin alpha+sin beta=a and cos alpha-cos beta=b then tan((alpha-beta)/(2))=

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

(sin (alpha + beta)) / (sin (alpha-beta)) = (a + b) / (ab) rArr (tan alpha) / (tan beta) =
