integral of x/2 e^{x^2}

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

\frac{1}{4} e^{x^{2}} + C

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int \frac{e ^{u}}{2} d u

= \frac{1}{2} \cdot \int \frac{e ^{u}}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \frac{1}{2} \cdot \int e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= \frac{1}{2} \cdot \frac{1}{2} e^{u}

Substitute back

u = x^{2}

= \frac{1}{2} \cdot \frac{1}{2} e^{x^{2}}

Simplify

\frac{1}{2} \cdot \frac{1}{2} e^{x^{2}} : \frac{1}{4} e^{x^{2}}

= \frac{1}{4} e^{x^{2}}

Add a constant to the solution

= \frac{1}{4} e^{x^{2}} + C

\int \frac{x - 5}{2 ^{x - 1}} d x

\int sec^{n} (d) x d x

\int 10 - 1.5 x^{\frac{1}{2}} d x

\int x^{4} ln (6 x) d x

\int x e^{(- 5 x)} d x
