21 sie 2024 · Sin A + Sin B Formula is a very significant formula in trigonometry, enabling the calculation of the sum of sine values for angles A and B. Sin A + Sin B Formula provides a way to express the sum of two sine functions in terms of the product of sine and cosine functions.
9 maj 2016 · Use this formula: $$2 \sin (A+B)\sin (A-B)=\cos2B-\cos2A$$. It will be like this: $$\dfrac12 \cdot (\cos2B-\cos2A)$$ $$=\dfrac { (1-2\sin^2B)- (1-2\sin^2A)} {2}$$. It will give the answer if you simplify. Share. Cite. Follow.
