integral of (5/(sqrt(1-x^2))-2/(x^2+1))

\int (\frac{5}{1 - x ^{2}} - \frac{2}{x ^{2} + 1}) d x

5 arcsin (x) - 2 arctan (x) + C

Solution steps

\int \frac{5}{1 - x ^{2}} - \frac{2}{x ^{2} + 1} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{5}{1 - x ^{2}} d x - \int \frac{2}{x ^{2} + 1} d x

\int \frac{5}{1 - x ^{2}} d x = 5 arcsin (x)

\int \frac{2}{x ^{2} + 1} d x = 2 arctan (x)

= 5 arcsin (x) - 2 arctan (x)

Add a constant to the solution

= 5 arcsin (x) - 2 arctan (x) + C

\int x^{2} r^{2} - x^{2} d x

\int x^{2} - 3 y^{2} d y

\int tan (x) \cdot (sec (x))^{2} d x

\int x \cdot (x + 1) d x

\int (38 - 5 x) - 28 d x
