sinA sin(A + 2 B) – sin B sin(B + 2A) = ...

`sinA sin(A + 2 B) – sin B sin(B + 2A) = sin (A - B) sin (A + B)`

sinA sin(A + 2 B) – sin B sin(B + 2A) = sin (A - B) sin (A + B)
Text Solution
|
sin A sin (A + 2B) -sin B sin (B + 2A) = sin (AB) sin (A + B)
Text Solution
|
sin A sin (A + 2B) sin B sin (B + 2A) = sin (AB) sin (A + B)
