Find the integral of \frac{\cos(2\theta )}{\cos(\theta )} using the table of common integrals rule \int a\mathrm{d}t=at.

$$\frac{\cos(2\theta )}{\cos(\theta )}t$$

সিমপ্লিফাই।

$$\frac{\cos(2\theta )t}{\cos(\theta )}$$

If F\left(t\right) is an antiderivative of f\left(t\right), then the set of all antiderivatives of f\left(t\right) is given by F\left(t\right)+C. Therefore, add the constant of integration C\in \mathrm{R} to the result.
