integral from 0 to ln(20) of xe^x

\int_{0}^{l n (20)} x e^{x} d x

20 ln (20) - 19

Decimal Notation

40.91464 \dots

Solution steps

\int_{0}^{l n (20)} x e^{x} d x

Apply Integration By Parts

: [e^{x} x - \int e^{x} d x]_{0}^{l n (20)}

= [e^{x} x - \int e^{x} d x]_{0}^{l n (20)}

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

= [e^{x} x - e^{x}]_{0}^{l n (20)}

Compute the boundaries:

20 ln (20) - 19

= 20 ln (20) - 19

\int \frac{12 x ^{2} + 4 x + 2}{x + x ^{2} + 2 x ^{3}} d x

\frac{\partial}{\partial x} (5 x + 4 y)

\int (x^{2} + 3 x - 2)^{2} d x

g (x) = y = 2 x, x = 1

\frac{\partial}{\partial y} (ln (1 + y^{2}))
