If `alpha` and `beta` are solutions of `sin^2 x + a sin x+b=0` as well as that of `cos^2x + c cosx + d =0` then `sin(alpha + beta) ` is equal to

If alpha and beta are solutions of sin^(2)x+a sin x+b=0 as well as that of cos^(2)x+c cos x+d=0 then sin(alpha+beta) is equal to

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

If alpha and beta are two solutions of the equation a tan x+b sec x=c ,then find the values of sin(alpha+beta) and cos(alpha+beta)

If x cos alpha + y sin alpha = x cos beta + y sin beta = 2a then cos alpha cos beta =

If alpha and beta are the solutions roots of a cos theta+b sin theta=c, then choose the correct option (A)sin alpha+sin beta=(2bc)/(a^(2)+b^(2))(B)sin alpha sin beta=(c^(2)-a^(2))/(a^(2)+b^(2))(C)sin alpha+sin beta=(a^(2)-b^(2))/(c^(2)+b^(2))(D)sin alpha sin beta=(a^(2)-b^(2))/(c^(2)+b^(2))(D)

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 cos(alpha+beta)=0 then sin^(2)alpha+sin^(2)beta

alpha is a root of equation ( 2 sin x - cos x ) (1+ cos x)=sin^2 x , beta is a root of the equation 3 cos ^2x - 10 cos x +3 =0 and gamma is a root of the equation 1-sin2 x = cos x- sin x : 0 le alpha , beta, gamma , le pi//2 sin alpha + sin beta + sin gamma can be equal to
