integral from 0 to 5 of 2.5x

\int_{0}^{5} 2.5 x d x

31.25

Solution steps

\int_{0}^{5} 2.5 x d x

Take the constant out:

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

= 2.5 \cdot \int_{0}^{5} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{5}

= 2.5 [\frac{x ^{2}}{2}]_{0}^{5}

Simplify

= 2.5 [0.5 x^{2}]_{0}^{5}

Compute the boundaries:

12.5

= 2.5 \cdot 12.5

Simplify

= 31.25

\int_{x}^{x^{3}} \frac{y}{x} d y

\int_{1}^{\infty} \frac{1}{x ^{m}} d x

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

\int_{0}^{x} t^{2} e^{t^{2}} d t

\int_{0}^{a} x e^{\frac{x}{a}} d x
