NettetSolution Step 1: Substitute u in the place 2 x in the given integration Let I = ∫ cos 2 x d x …. (1) and 2 x = u Now differentiate the equation 2 x = u with respect to x 2 d x = d u ⇒ d x = 1 2 d u Now putting d x = 1 2 d u in equation (1) I = 1 2 ∫ cos u d u Step 2: Apply the formula ∫ cos x d x = sin x + c I = 1 2 ∫ cos u d u NettetAnswer: The value of the given integral is x - x 3 / (3 · 3!) + x 5 / (5 · 5!) - x 7 / (7 · 7!) + ... Practice Questions on Integration of Sin x FAQs on Integral of Sin x What is the Integral of Sin x? The integral of sin x is -cos x + C. It is mathematically written as ∫ sin x dx = -cos x + C. Here, C is the integration constant.

NettetExamples. The function () = is an antiderivative of () =, since the derivative of is , and since the derivative of a constant is zero, will have an infinite number of antiderivatives, such as , +,, etc.Thus, all the antiderivatives of can be obtained by changing the value of c in () = +, where c is an arbitrary constant known as the constant of integration.

Nettet24. okt. 2014 · Basically you can't integrate the cos (x)^3 and the cos (x)^5. The reason for this is because they represent cos (x)*cos (x)*cos (x) and you cant integrate that without the u substitution. So in the end your only choice is to sub the trig identity for the cos … NettetAnswer: The integral of integral sin^2x cos^2x dx is x/8 - (sin 4x) / 32 + C. Example 3: Evaluate the integral ∫ sin 2 x cos 3 x dx. Solution: The given integral can be written as ∫ sin 2 x cos 2 x (cos x dx) We know that cos 2 x = 1 - sin 2 x. Then the above integral becomes ∫ sin 2 x (1 - sin 2 x) (cos x dx) = ∫ (sin 2 x - sin 4 x) (cos x dx) Nettet7. sep. 2024 · To integrate \(\displaystyle \int \cos^jx\sin^kx\,dx\) use the following strategies: 1.
