integral of cos(y^2)

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

\frac{π}{2} C (\frac{2}{π} y) + C

Solution steps

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

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} y)

Add a constant to the solution

= \frac{π}{2} C (\frac{2}{π} y) + C
