Detailed explanation-1: -What is the Integral of Sin x? The integral of sin x is-cos x. Mathematically, this is written as ∫ sin x dx =-cos x + C, were, C is the integration constant.
Detailed explanation-2: -Integration of x sin x Formula The formula for the integral of x sin x is given by, ∫xsinx dx = −x cos x + sin x + C, where C is the integration constant.
Detailed explanation-3: -Integral of sin x cos x can be determined using the sin 2x formula, and substitution method. Integration of sin x cos x given by: ∫ sin x cos x dx = (-1/4) cos 2x + C [When evaluated using the sin 2x formula]
Detailed explanation-4: -Integrals of trig functions can be found exactly as the reverse of derivatives of trig functions. The integral of sinx is −cosx+C and the integral of cosx is sinx+C.
