integral of e^{u^2}

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

\frac{π}{2} erfi (u) + C

Solution steps

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

Use the nonelementary integral:

\int e^{u^{2}} d u = \frac{π}{2} erfi (u)

= \frac{π}{2} erfi (u)

Add a constant to the solution

= \frac{π}{2} erfi (u) + C

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

t an g e n t f (x) = \frac{2}{x}, at x = - 2

y^{^{''}} + y = 2^{x}

\int_{1}^{3} (x^{5} + \frac{1}{4 x ^{5}}) d x

t an g e n t f (x) = \frac{3}{x}, (- 5, - \frac{3}{5})
