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 2 (16) Note that (13) and (14) come from (4) and (5) (to get (13), use (4) to expand cosA= cos(A+ B 2 + 2) and (5) to expand cosB= cos(A+B 2 2), and add the results). …
