integral of xe^{tx}

\int x e^{t x} d x

e^{t x} \frac{1}{t} x - e^{t x} \frac{1}{t ^{2}} + C

Solution steps

\int x e^{t x} d x

Apply Integration By Parts

= e^{t x} \frac{1}{t} x - \int e^{t x} \frac{1}{t} d x

\int e^{t x} \frac{1}{t} d x = e^{t x} \frac{1}{t ^{2}}

= e^{t x} \frac{1}{t} x - e^{t x} \frac{1}{t ^{2}}

Add a constant to the solution

= e^{t x} \frac{1}{t} x - e^{t x} \frac{1}{t ^{2}} + C
