integral from 0 to 1 of 7x^3

\int_{0}^{1} 7 x^{3} d x

\frac{7}{4}

Decimal

1.75

Solution steps

\int_{0}^{1} 7 x^{3} d x

Take the constant out:

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

= 7 \cdot \int_{0}^{1} x^{3} d x

Apply the Power Rule

: [\frac{x ^{4}}{4}]_{0}^{1}

= 7 [\frac{x ^{4}}{4}]_{0}^{1}

Compute the boundaries:

\frac{1}{4}

= 7 \cdot \frac{1}{4}

Simplify

= \frac{7}{4}

\int_{0}^{1} 9 x (x^{2} - 1)^{7} d x

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

\int_{- 2 π}^{2 π} 2 sin (x) d x

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

\int_{- 1}^{0} 2 x^{3} - 3 x^{2} - 12 x d x
