integral from 0 to 2x of cos(x^2)

\int_{0}^{2 x} cos (x^{2}) d x

\frac{π}{2} C (\frac{2}{π} \cdot 2 x) - \frac{π}{2} C (\frac{2}{π} \cdot 0)

Solution steps

\int_{0}^{2 x} cos (x^{2}) d x

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} x)]_{0}^{2 x}

Compute the boundaries:

\frac{π}{2} C (\frac{2}{π} \cdot 2 x) - \frac{π}{2} C (\frac{2}{π} \cdot 0)

= \frac{π}{2} C (\frac{2}{π} \cdot 2 x) - \frac{π}{2} C (\frac{2}{π} \cdot 0)
