integral from 0 to 2 of 30000e^{0.03x}

\int_{0}^{2} 30000 e^{0.03 x} d x

61836.54654 \dots

Solution steps

\int_{0}^{2} 30000 e^{0.03 x} d x

Take the constant out:

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

= 30000 \cdot \int_{0}^{2} e^{0.03 x} d x

Apply u-substitution

= 30000 \cdot \int_{0}^{0.06} e^{u} \frac{1}{0.03} d u

Take the constant out:

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

= 30000 \cdot \frac{1}{0.03} \cdot \int_{0}^{0.06} e^{u} d u

Simplify

= 30000 \cdot 33.33333 \dots \cdot \int_{0}^{0.06} e^{u} d u

Use the common integral:

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

= 30000 \cdot 33.33333 \dots [e^{u}]_{0}^{0.06}

Simplify

= 1000000 [e^{u}]_{0}^{0.06}

Compute the boundaries:

0.06183 \dots

= 1000000 \cdot 0.06183 \dots

Simplify

= 61836.54654 \dots
