integral of (1/(3x^2))

\int (\frac{1}{3 x ^{2}}) d x

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

Solution steps

\int \frac{1}{3 x ^{2}} d x

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{x ^{2}} d x

Apply the Power Rule

: - \frac{1}{x}

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

Simplify

\frac{1}{3} (- \frac{1}{x}) : - \frac{1}{3 x}

= - \frac{1}{3 x}

Add a constant to the solution

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

\int d (x^{6}) d x

\int (2 x^{2} + 4)^{8} d x

\int \frac{x ^{2} - 36}{2 x} d x

\int y e^{x^{3}}

\int 5 x^{4} e^{5 x^{5}} d x
