integral of 0.4x^2

Solution

\int 0.4 x^{2} d x

Solution

0.13333 \dots x^{3} + C

Solution steps

\int 0.4 x^{2} d x

Take the constant out:

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

= 0.4 \cdot \int x^{2} d x

Apply the Power Rule

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

= 0.4 \cdot \frac{x ^{3}}{3}

Simplify

0.4 \cdot \frac{x ^{3}}{3} : 0.13333 \dots x^{3}

= 0.13333 \dots x^{3}

Add a constant to the solution

= 0.13333 \dots x^{3} + C
