[" (59) If "alpha,beta" are different values of 'x'satisfying,a "],[cos x+b sin x=c," then "tan((alpha+beta)/(2))]

If alpha,beta are the different values of x satisfying a cos x+b sin x=c then tan((alpha+beta)/(2)) is

If alpha,beta are the different values of x satisfying acosx+bsinx=c then tan((alpha+beta)/2) is

If alpha and beta are two real numbers satisfying the equation a cos x + b sin x = c, prove that : tan (alpha+ beta)= (2ab)/(a^2-b^2) .

If alpha, beta are two different values of theta which satisfy is bc cos theta cos phi + ac sin theta sin phi=ab , then prove that (b^(2)+c^(2)-a^(2)) cos alpha cos beta+ ac sin alpha sin beta= a^(2)+b^(2)-c^(2) .

If alpha , beta alpha ne beta satisfies the question a costheta + b sin theta = c , then the value of tan ( (alpha + beta)/(2) ) is :

If alpha, beta are solutions of a cos x + b sin x = c then sin alpha + sin beta =

If alpha, beta are solutions of a cos x + b sin x = c then cos alpha + cos beta=

If alpha, beta (alpha ne beta) satisfy the equation a cos theta + b sin theta=c then the value of tan ""(alpha + beta)/(2) is-

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