integral of e^{2y}cos(e^{2y})

\int e^{2 y} cos (e^{2 y}) d y

\frac{1}{2} sin (e^{2 y}) + C

Solution steps

\int e^{2 y} cos (e^{2 y}) d y

Apply u-substitution

= \int e^{u} cos (e^{u}) \frac{1}{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} cos (e^{u}) d u

Apply u-substitution

= \frac{1}{2} \cdot \int cos (v) d v

Use the common integral:

\int cos (v) d v = sin (v)

= \frac{1}{2} sin (v)

Substitute back

= \frac{1}{2} sin (e^{2 y})

Add a constant to the solution

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