Sin a + sinb
Webb5 apr. 2024 · sin ( A − B) = sin A cos B − cos A sin B It is called sine of angle difference identity. It states that the sin of subtraction of two angles is equal to the subtraction of products of sine and cosine of both angles. Introduction Sine functions are often appeared with subtraction of two angles. WebbCorrect option is C) sin(A+B).sin(A−B)=[sin(A)cos(B)+cos(A)sin(B)][sin(A)cos(B)−cos(A)sin(B)]=sin 2Acos …
