integral of 3ye^{3y^2}

\int 3 y e^{3 y^{2}} d y

\frac{1}{2} e^{3 y^{2}} + C

Solution steps

\int 3 y e^{3 y^{2}} d y

Take the constant out:

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

= 3 \cdot \int y e^{3 y^{2}} d y

Apply u-substitution

= 3 \cdot \int \frac{e ^{u}}{6} d u

Take the constant out:

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

= 3 \cdot \frac{1}{6} \cdot \int e^{u} d u

Use the common integral:

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

= 3 \cdot \frac{1}{6} e^{u}

Substitute back

u = 3 y^{2}

= 3 \cdot \frac{1}{6} e^{3 y^{2}}

Simplify

3 \cdot \frac{1}{6} e^{3 y^{2}} : \frac{1}{2} e^{3 y^{2}}

= \frac{1}{2} e^{3 y^{2}}

Add a constant to the solution

= \frac{1}{2} e^{3 y^{2}} + C
