integral from 1 to 10 of 3x

\int_{1}^{10} 3 x d x

\frac{297}{2}

Decimal Notation

148.5

Solution steps

\int_{1}^{10} 3 x d x

Take the constant out:

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

= 3 \cdot \int_{1}^{10} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{1}^{10}

= 3 [\frac{x ^{2}}{2}]_{1}^{10}

Compute the boundaries:

\frac{99}{2}

= 3 \cdot \frac{99}{2}

Simplify

= \frac{297}{2}

\int_{2}^{6} 16 - 2 x d x

\int_{5}^{7} x (x - 5)^{12} d x

\int_{0}^{1} y (- 3 y^{2} + 2 y + 1) d y

\int_{0}^{\frac{π}{2}} y cos (y) d y

\int_{0}^{\frac{π}{6}} 9 sin^{2} (x) d x
