integral of ln(x^{-2})

\int ln (x^{- 2}) d x

- 2 x ln (x) + 2 x + C

Solution steps

\int ln (x^{- 2}) d x

Simplify

ln (x^{- 2}) : - ln (x^{2})

= \int - ln (x^{2}) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int ln (x^{2}) d x

Apply Integration By Parts

: x ln (x^{2}) - \int 2 d x

= - (x ln (x^{2}) - \int 2 d x)

\int 2 d x = 2 x

= - (x ln (x^{2}) - 2 x)

Simplify

- (x ln (x^{2}) - 2 x) : - 2 x ln (x) + 2 x

= - 2 x ln (x) + 2 x

Add a constant to the solution

= - 2 x ln (x) + 2 x + C

\int \frac{8}{3} sin (x) d x

x \to - 4 lim (\frac{1}{4} x^{5} - 2 x)

r + 3 r

\int 1000 - 50 x d x

(arctan (2 x))^{2}
