integral of xe^{2-x}

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

e^{2} (- e^{- x} x - e^{- x}) + C

Solution steps

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

Simplify

e^{2 - x} : e^{2} e^{- x}

= \int x e^{2} e^{- x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= e^{2} \cdot \int x e^{- x} d x

Apply Integration By Parts

: - e^{- x} x - \int - e^{- x} d x

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

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

= e^{2} (- e^{- x} x - e^{- x})

Add a constant to the solution

= e^{2} (- e^{- x} x - e^{- x}) + C

\int \frac{1}{3} x d x

y = x^{2} sin (2 x)

\frac{d}{d x} (\frac{a}{( x ^{2} + a ^{2} ) ^{2}})

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

\frac{\partial}{\partial x} (3^{2 x} + 5^{4 y} + 2 x + y^{4})
