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

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

\frac{x ^{2}}{6} + C

Solution steps

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

Cancel the common factor:

x

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

Apply the Power Rule

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

Simplify

\frac{1}{3} \cdot \frac{x ^{2}}{2} : \frac{x ^{2}}{6}

= \frac{x ^{2}}{6}

Add a constant to the solution

= \frac{x ^{2}}{6} + C

\int 1 + 16 x d x

\int \frac{2}{3 + 3 e ^{x}} d x

\int x^{2} 9 - x d x

\int \frac{3 x ^{2}}{( 6 - 5 x ^{3} ) ^{4}} d x

\int 3 t^{3} - t d t
