WebbSin (A + B) Formula : The formula of sin (A + B) is sin A cos B + cos A sin B. Example : If sin A = 3 5 and cos B = 9 41, find the value of sin (A + B). Solution : We have, sin A = 3 5 and cos B = 9 41. ∴ cos A = 1 – s i n 2 A and sin B = 1 – c o s 2 B. cos A = 1 – 9 25 = 4 5 and sin B = 1 – 81 1681 = 40 41. Now, By using above formula, WebbSin (A + B) Formula : The formula of sin (A + B) is sin A cos B + cos A sin B. Example : If sin A = 3 5 and cos B = 9 41, find the value of sin (A + B).
