integral of e^{y^2}y

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

\frac{1}{2} e^{y^{2}} + C

Solution steps

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

Apply u-substitution

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

= \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 \int e^{u} d u

Use the common integral:

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

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

Substitute back

u = y^{2}

= \frac{1}{2} e^{y^{2}}

Add a constant to the solution

= \frac{1}{2} e^{y^{2}} + C

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

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

\frac{d}{d y} (2 y)

x \to 3 - lim (\frac{∣ 3 - x ∣}{3 - x})

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