integral of x^2-1/(x^2)

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

\frac{x ^{3}}{3} + \frac{1}{x} + C

Solution steps

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

\int x^{2} d x = \frac{x ^{3}}{3}

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

= \frac{x ^{3}}{3} - (- \frac{1}{x})

Simplify

= \frac{x ^{3}}{3} + \frac{1}{x}

Add a constant to the solution

= \frac{x ^{3}}{3} + \frac{1}{x} + C

\int z d z

\frac{d}{d x} ((x + 4)^{\frac{2}{3}} (2 x^{2} - 1)^{3})

in v erse l a pl a ce \frac{1}{( s - 1 ) ^{2} + 4}

t an g e n t f (x) = x^{2} + 1, at x = - 5

\int_{0}^{1} cos (π x) d x
