integral of cos(u^2)

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

\frac{π}{2} C (\frac{2}{π} u) + C

Solution steps

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

Use the nonelementary integral:

\int cos (x^{2}) d x = \frac{π}{2} C (\frac{2}{π} x)

= \frac{π}{2} C (\frac{2}{π} u)

Add a constant to the solution

= \frac{π}{2} C (\frac{2}{π} u) + C
