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

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

\frac{x ^{3}}{6} + C

Solution steps

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

Take the constant out:

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

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

Simplify

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

Apply the Power Rule

: \frac{x ^{3}}{3}

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

Simplify

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

= \frac{x ^{3}}{6}

Add a constant to the solution

= \frac{x ^{3}}{6} + C

\int 3 x^{5} x^{- \frac{4}{3}} (x^{3} - 1) d x

\int \frac{1}{( 5 x + 7 ) ^{2}} d x

\int \frac{4}{5} + \frac{3}{4} x^{2} - \frac{6}{7} x^{3} d x

\int (e^{\frac{x}{n}} - a^{\frac{x}{n}}) d x

\int sec^{2} (- 0.578 t) d t
