If `alpha, beta ` are solutin of `6 cos theta + 8 sin theta=9,` then `sin (alpha + beta)=`

If alpha,beta are roots of a cos theta+b sin theta=c then value of sin alpha+sin beta&sin alpha sin beta is

alpha & beta are solutions of a cos theta+b sin theta=c(cosalpha != cos beta)&(sin alpha != sin beta) Then tan((alpha+beta)/2)=?

alpha& beta are solutions of a cos theta+b sin theta=c(cos alpha!=cos beta)&(sin alpha!=sin beta) Then tan((alpha+beta)/(2))=?

If alpha , beta are two different values of theta lying between 0 and 2pi which satisfy the equation 6 cos theta + 8 sin theta=9, find the value of sin ( alpha + beta).

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

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