integral of 13z^3e^z

\int 13 z^{3} e^{z} d z

13 (z^{3} e^{z} - 3 (z^{2} e^{z} - 2 (e^{z} z - e^{z}))) + C

Solution steps

\int 13 z^{3} e^{z} d z

Take the constant out:

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

= 13 \cdot \int z^{3} e^{z} d z

Apply Integration By Parts

: z^{3} e^{z} - \int 3 z^{2} e^{z} d z

= 13 (z^{3} e^{z} - \int 3 z^{2} e^{z} d z)

\int 3 z^{2} e^{z} d z = 3 (z^{2} e^{z} - 2 (e^{z} z - e^{z}))

= 13 (z^{3} e^{z} - 3 (z^{2} e^{z} - 2 (e^{z} z - e^{z})))

Add a constant to the solution

= 13 (z^{3} e^{z} - 3 (z^{2} e^{z} - 2 (e^{z} z - e^{z}))) + C

d \to 0 lim (\frac{1}{x + 6} + d)

\frac{\partial}{\partial y} (x sin (\frac{x}{y}))

\int x sin (3 a x) d x

\frac{\partial}{\partial x} (x ln (z^{4} + x^{3}))

f (x) = (\frac{x + 3}{x - 3})^{2}, at x = 4
