integral of x*a^x

\int x \cdot a^{x} d x

\frac{a ^{x} x}{ln ( a )} - \frac{a ^{x}}{ln ^{2} ( a )} + C

Solution steps

\int x a^{x} d x

Apply Integration By Parts

: \frac{a ^{x} x}{ln ( a )} - \int \frac{a ^{x}}{ln ( a )} d x

= \frac{a ^{x} x}{ln ( a )} - \int \frac{a ^{x}}{ln ( a )} d x

\int \frac{a ^{x}}{ln ( a )} d x = \frac{a ^{x}}{ln ^{2} ( a )}

= \frac{a ^{x} x}{ln ( a )} - \frac{a ^{x}}{ln ^{2} ( a )}

Add a constant to the solution

= \frac{a ^{x} x}{ln ( a )} - \frac{a ^{x}}{ln ^{2} ( a )} + C

\int e^{5 t} cos (t) d t

\int \frac{1}{4 - 49 x ^{2}} d x

y = e^{- k x^{2}}

1 + x^{2}

\frac{d}{d x} (e^{x^{5} + 3 x})
