integral from 0 to 2pi of 7xsqrt(2)

\int_{0}^{2 π} 7 x 2 d x

142 π^{2}

Decimal Notation

195.40819 \dots

Solution steps

\int_{0}^{2 π} 7 x 2 d x

Take the constant out:

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

= 72 \cdot \int_{0}^{2 π} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{2 π}

= 72 [\frac{x ^{2}}{2}]_{0}^{2 π}

Compute the boundaries:

2 π^{2}

= 72 \cdot 2 π^{2}

Simplify

= 142 π^{2}

\int_{0}^{1} e^{- 10 x} d x

\int_{- 1}^{0} x 1 + 9 x^{4} d x

\int_{2}^{5} (2 x^{3} - 4 x + \frac{1}{x}) d x

\int_{- 1}^{0} ln (- x) d x

\int_{0}^{\frac{1}{6}} \frac{x ^{3}}{x ^{2} - 1} d x
