Find the integral of \frac{\cos(\theta )}{\left(\sin(\theta )\right)^{2}} using the table of common integrals rule \int a\mathrm{d}x=ax.

$$\frac{\cos(\theta )}{\left(\sin(\theta )\right)^{2}}x$$

تبسيط.

$$\frac{\cos(\theta )x}{\left(\sin(\theta )\right)^{2}}$$

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