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, Webb27 mars 2016 · But it is true that sin(a + b) +sin(a − b) = 2sinacosb Explanation: sin(a + b) = sinacosb + cosasinb. So, sin(a + b) +sin(a + b) = 2sin(a + b) = 2(sinacosb + cosasinb) = 2sinacosb + 2cosasinb. The last is equal to 2sinacosb only if cosa = 0 or sinb = 0 But sin(a − b) = sinacosb − cosasinb. So,
