integral of (e^xsin(e^x))

\int (e^{x} sin (e^{x})) d x

- cos (e^{x}) + C

Solution steps

\int e^{x} sin (e^{x}) d x

Apply u-substitution

: \int sin (u) d u

= \int sin (u) d u

Use the common integral:

\int sin (u) d u = - cos (u)

= - cos (u)

Substitute back

u = e^{x}

= - cos (e^{x})

Add a constant to the solution

= - cos (e^{x}) + C

\int \frac{x}{x ^{4} - 36 x ^{2}} d x

\int ln (2 x - 4) d x

\int e^{\frac{- x}{a}} x^{2} d x

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

\int \frac{3}{( 2 x + 1 )} d x
