integral of ze^{z^2+1}

\int z e^{z^{2} + 1} d z

\frac{1}{2} e^{z^{2} + 1} + C

Solution steps

\int z e^{z^{2} + 1} d z

Apply u-substitution

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

= \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

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

Use the common integral:

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

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

Substitute back

u = z^{2} + 1

= \frac{1}{2} e^{z^{2} + 1}

Add a constant to the solution

= \frac{1}{2} e^{z^{2} + 1} + C

\int (4 x^{\frac{1}{3}} + 6 x^{- 7} + 10) d x

\int \frac{1}{x ^{2} 25 x ^{2} + 4} d x

\int x s arccos (x) d x

\int \frac{2 x ^{3} - 5 x ^{2} + 4 x - 4}{x ^{2} - x} d x

\int (e^{x} + x^{2}) d x
