integral from 0 to 1 of 15xe^x

\int_{0}^{1} 15 x e^{x} d x

15

Solution steps

\int_{0}^{1} 15 x e^{x} d x

Take the constant out:

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

= 15 \cdot \int_{0}^{1} x e^{x} d x

Apply Integration By Parts

: [e^{x} x - \int e^{x} d x]_{0}^{1}

= 15 [e^{x} x - \int e^{x} d x]_{0}^{1}

\int e^{x} d x = e^{x}

= 15 [e^{x} x - e^{x}]_{0}^{1}

Compute the boundaries:

1

= 15 \cdot 1

Simplify

= 15

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

\int_{- 2}^{2} x^{2} + x + 2 d x

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

\int_{5}^{7} ∣ f (3 x) ∣ d x

\int_{0}^{15} x d x
