integral from 0 to ln(5) of e^x

解答

\int_{0}^{l n (5)} e^{x} d x

4

求解步骤

\int_{0}^{l n (5)} e^{x} d x

使用积分常见定则:

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

= [e^{x}]_{0}^{l n (5)}

带入上下限计算后得:

4

= 4

\frac{d}{d x} (34 (4 e^{x^{2}} x^{3} + 6 e^{x^{2}} x))

\int sin (ln (4 x)) d x

\frac{d}{d x} (e^{3 x} cos (2 x))

\int e (x) d x

\int \frac{x - 6}{x ^{2} + x - 6} d x
