integral from 0 to ln(19) of xe^x

\int_{0}^{l n (19)} x e^{x} d x

19 ln (19) - 18

Decimal Notation

37.94434 \dots

Solution steps

\int_{0}^{l n (19)} x e^{x} d x

Apply Integration By Parts

: [e^{x} x - \int e^{x} d x]_{0}^{l n (19)}

= [e^{x} x - \int e^{x} d x]_{0}^{l n (19)}

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

= [e^{x} x - e^{x}]_{0}^{l n (19)}

Compute the boundaries:

19 ln (19) - 18

= 19 ln (19) - 18

\int t sin (n t) d t

\frac{\partial}{\partial x} (cot (x))

\frac{5}{x}

\frac{d}{d x} (\frac{1}{( x - 6 ) ^{2}})

f (x) = x^{2} + 3 x + 4 π, at x = 2.5
