integral of y^2e^y

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

y^{2} e^{y} - 2 (e^{y} y - e^{y}) + C

Solution steps

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

Apply Integration By Parts

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

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

\int 2 y e^{y} d y = 2 (e^{y} y - e^{y})

= y^{2} e^{y} - 2 (e^{y} y - e^{y})

Add a constant to the solution

= y^{2} e^{y} - 2 (e^{y} y - e^{y}) + C

\frac{d}{d x} (ln (sin (6 x)))

(- 6, 6), (4, - 7)

3 y^{^{''}} = 2 y^{^{'}}

\int cos (x^{2}) d x

\int \frac{x ^{2}}{x ^{2} + 8} d x
