integral of (3e^{ln(x)})/x

解答

\int \frac{3 e ^{l n (x)}}{x} d x

3 x + C

求解步骤

\int \frac{3 e ^{l n (x)}}{x} d x

\frac{3 e ^{l n (x)}}{x} = 3

= \int 3 d x

常数积分:

\int a d x = a x

= 3 x

解答补常数

= 3 x + C

\int \frac{2 x + 2}{x ^{2} + 2 x + 3} d x

\int \frac{e ^{x}}{( e ^{x} + 1 ) ^{7}} d x

\int e^{\frac{1}{100} x} d x

\int cos (2 θ) (sin (θ) + cos (θ))^{2} d θ

\int 9 x^{- 6} - 81 x^{- 8} d x
