Question: \begin{align} \int \left(\frac {2-3sin x}{cos^2 x}\right) . dx\end{align}

Answer:

\begin{align} \int \left(\frac {2-3sin x}{cos^2 x}\right) . dx\end{align}

\begin{align} =\int \left(\frac {2}{cos^2 x} - \frac{3sinx}{cos^2x}\right) . dx\end{align}

\begin{align} =2\int sec^2 x .dx - 3 \int tan x . sec x. dx\end{align}

\begin{align} =2 tan x - 3 sec x + C\end{align}
