integral from 0 to 3 of 3x^2

\int_{0}^{3} 3 x^{2} d x

27

Solution steps

\int_{0}^{3} 3 x^{2} d x

Take the constant out:

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

= 3 \cdot \int_{0}^{3} x^{2} d x

Apply the Power Rule

: [\frac{x ^{3}}{3}]_{0}^{3}

= 3 [\frac{x ^{3}}{3}]_{0}^{3}

Compute the boundaries:

9

= 3 \cdot 9

Simplify

= 27

\frac{\partial}{\partial x} (x^{\frac{2}{5}} \cdot y^{\frac{3}{5}})

\int \frac{( 3 x + 5 )}{x ^{2} + x + 1} d x

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

y = 5 x - 2, (5, 23)
