integral from 0 to 1 of (4x^e+9e^x)

\int_{0}^{1} (4 x^{e} + 9 e^{x}) d x

\frac{4}{e + 1} + 9 (e - 1)

Decimal

16.54030 \dots

Solution steps

\int_{0}^{1} 4 x^{e} + 9 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

= \int_{0}^{1} 4 x^{e} d x + \int_{0}^{1} 9 e^{x} d x

\int_{0}^{1} 4 x^{e} d x = \frac{4}{e + 1}

\int_{0}^{1} 9 e^{x} d x = 9 (e - 1)

= \frac{4}{e + 1} + 9 (e - 1)

\int_{- 1}^{1} (3 t - 3) d t

\int_{0}^{1} 5 x^{5} d x

\int_{- 10}^{- 6} \frac{1}{x + 2} d x

\int_{- 1}^{2} (3 x - 8) (x + 3) d x

\int_{4}^{7} (x^{2} + \frac{1}{x}) d x
