WebbExample 1: Evaluate the integral ∫sin 12x cos 3x dx using the sin a cos b formula. Solution: First, we will express sin 12x cos 3x as a sum of sine function using the formula sin a cos b = sin a cos b = (1/2) [sin (a + b) + sin (a - b)]. Identify a and b in sin 12x cos 3x. We have a = 12x, b = 3x. Substitute the values of a and b in the formula sin a cos b = (1/2) [sin (a + b) … 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.
