integral of (8x^2+3x^{-2})

\int (8 x^{2} + 3 x^{- 2}) d x

\frac{8 x ^{3}}{3} - \frac{3}{x} + C

Solution steps

\int 8 x^{2} + 3 x^{- 2} d x

3 x^{- 2} = \frac{3}{x ^{2}}

= \int 8 x^{2} + \frac{3}{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 8 x^{2} d x + \int \frac{3}{x ^{2}} d x

\int 8 x^{2} d x = \frac{8 x ^{3}}{3}

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

= \frac{8 x ^{3}}{3} - \frac{3}{x}

Add a constant to the solution

= \frac{8 x ^{3}}{3} - \frac{3}{x} + C

x \to 0 - lim (x^{2} e^{\frac{1}{x}})

40 t + t^{2} - \frac{1}{12} t^{3}

\int \frac{10}{cos ( x ) - 1} d x

\frac{d y}{d x} = y x

f (t) = 7 sin (\frac{3 t}{2})
