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 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 and beta are roots of the equation a cos theta + b sin theta = c , then find the value of tan (alpha + beta).

If alpha and beta are roots of the equatioin a cos theta + b sin theta = c , then find the value of tan (alpha + beta).

If alpha and beta are roots of the equatioin a cos theta + b sin theta = c , then find the value of tan (alpha + beta).

If alpha, beta are different values of theta satisfying the equation 5 cos theta + 12 sin theta = 11 then the value of sin (alpha + beta)=

If alpha, beta are the solutions of a cos 2theta + b sin 2theta = c , then tan alpha tan beta=

If alpha, beta are the roots of the equation a cos theta + b sin theta = c , then prove that cos(alpha + beta) = (a^2 - b^2)/(a^2+b^2) .

If alpha and beta are 2 distinct roots of equation a cos theta + b sin theta = C then cos( alpha + beta ) =
