[Solved] How to Integrate \int \sin^2x\cos\ x \ dx 9to5Science
The integral of sin2x is represented as ∫sin2xdx. The given integral is calculated using the substitution method. I = ∫sin2xdx. Let u = 2x. Now, differentiating both sides, we get. du = 2dx ⇒ dx = du 2. Substituting the value of u and du in the integral, we get, I = ∫ sinudu 2 = 1 2∫ sinudu = 1 2(− cosu) + C.

Și cum nouă ne trebuie sub integrală acel $4$ de la numărător, în afara integralei va rămâne doar $4$ de la numitor, adică afară va rămâne fracția $\frac{1}{4}$. Deci, integrala devine atunci $$\frac{4}{4}\int x^3\cdot e^{x^4}dx=\frac{1}{4}\int 4x^3\cdot e^{x^4}dx,$$ adică, sub integrală apare acum exact ceea ce ne trebuie nouă.
int(1+cos(2x))/(sin(2x))dx=? Socratic
The cos2(2x) term is another trigonometric integral with an even power, requiring the power--reducing formula again. The cos3(2x) term is a cosine function with an odd power, requiring a substitution as done before. We integrate each in turn below. cos3(2x) = cos2(2x)cos(2x) = (1 − sin2(2x))cos(2x).

Equation 1.8.3. cos(2x) = cos2x − sin2x = 2cos2x − 1 = 1 − 2sin2x. Notice that the last two lines of Equation 1.8.3 follow from the first line by replacing either sin2x or cos2x using Equation 1.8.1. It is also useful to rewrite these last two lines:

First we split sin2(x) = (1−e2ix)+(1−e−2ix) 4 sin 2 ( x) = ( 1 − e 2 i x) + ( 1 − e − 2 i x) 4. To avoid the pole at x = 0 x = 0, drop the path of integration a bit below the real line (this function has no poles and it vanishes at infinity, so this is okay). Next, let γ+ γ + be the path below the real axis, then circling back in.

As soon as you see a question asking you to integrate the square of sin, cos or tan, your first approach should be to use trigonometric identities and double angle formulas. For sin 2 (X), we will use the cos double angle formula: cos(2X) = 1 - 2sin 2 (X) The above formula can be rearranged to make sin 2 (X) the subject: sin 2 (X) = 1/2(1 - cos(2X)) You can now rewrite the integration:
