integral from 0 to 7 of 5(1-e^x)

\int_{0}^{7} 5 (1 - e^{x}) d x

5 (- e^{7} + 8)

Decimal

- 5443.16579 \dots

Solution steps

\int_{0}^{7} 5 (1 - e^{x}) d x

Take the constant out:

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

= 5 \cdot \int_{0}^{7} 1 - e^{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 5 (\int_{0}^{7} 1 d x - \int_{0}^{7} e^{x} d x)

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

\int_{0}^{7} e^{x} d x = e^{7} - 1

= 5 (7 - (e^{7} - 1))

Simplify

= 5 (- e^{7} + 8)

\int_{2 π}^{5 π} ∣ sin (x) ∣ d x

\int_{1}^{3} \frac{2}{t} d t

\int_{\frac{- π}{3}}^{\frac{π}{4}} cos (θ) d θ

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

\int_{0}^{π} 4 sin (x) - sin (4 x) d x
