integral of 4ye^{y^2}

\int 4 y e^{y^{2}} d y

2 e^{y^{2}} + C

Solution steps

\int 4 y e^{y^{2}} d y

Take the constant out:

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

= 4 \cdot \int y e^{y^{2}} d y

Apply u-substitution

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

= 4 \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

= 4 \cdot \frac{1}{2} \cdot \int e^{u} d u

Use the common integral:

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

= 4 \cdot \frac{1}{2} e^{u}

Substitute back

u = y^{2}

= 4 \cdot \frac{1}{2} e^{y^{2}}

Simplify

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

= 2 e^{y^{2}}

Add a constant to the solution

= 2 e^{y^{2}} + C
