$\int \frac{x^{2} + 1}{(v x : 4 + 9 x^{2})} d x$

Step 1

$\int \frac{x^{2} + 1}{(v x : 4 + 9 x^{2})} d x$ is an antiderivative of $\frac{x^{2} + 1}{(v x : 4 + 9 x^{2})}$ , so by definition $\frac{d}{d x} [\int \frac{x^{2} + 1}{(v x : 4 + 9 x^{2})} d x]$ is $\frac{x^{2} + 1}{(v x : 4 + 9 x^{2})}$ .

$\frac{x^{2} + 1}{(v x : 4 + 9 x^{2})}$
