integral of xe^{-y^2}

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

\frac{e ^{- y^{2}} x ^{2}}{2} + C

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

: \frac{x ^{2}}{2}

= e^{- y^{2}} \frac{x ^{2}}{2}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{e ^{- y^{2}} x ^{2}}{2}

Add a constant to the solution

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

\int \frac{4}{x x + 1} d x

\frac{x ^{- 1}}{2}

\int \frac{2 t + 3}{t} d t

\int sin (\frac{π}{4})

\int \frac{10 x ^{2}}{8 + 9 x} d x
