What is the cos(x)^2 integral? Integral of cos 2 x

In this math lesson, we will tell you what the integral of cos x 2 is. So what is the integral of cos(x)^2? What is the integral of cos(x) to the 2nd? Cosines ^ 2 x integral you can learn this lesson. You can see the proof and solution in our article. We wish you good integral solving in advance.

$cos^2x$ Integral | Integral of Cos2(x)

For the integral of cosx to the 2nd, we first need to write the expansion of cos^2(x).

$cos^2x$ expansion = $cos^2x=\frac{1+cos2x}{2}$

$cos^2x$ transform (conversion) = $cos^2x=\frac{1+cos2x}{2}$

Now that we have done the conversion, our job has become even easier. Now let's move on to the solution.

Now let's move on to the step-by-step solution:

→ $cos^2x=\frac{1+cos2x}{2}=\frac{1}{2}+\frac{cos2x}{2}$

→ $\int{(\frac{1}{2}+\frac{cos2x}{2})dx}$

→ $\int{\frac{1}{2}dx}+\int{\frac{cos2x}{2}dx}$

→ $\frac{x}{2}+\frac{sin2x}{4}$

As a result, our answer is $\frac{x}{2}+\frac{sin2x}{4}$. (Answer = x/2 + sin2x/4)

$cos^2x$ integral = $\frac{x}{2}+\frac{sin2x}{4}$
