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

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

\frac{π}{2} C (\frac{2}{π} \cdot 2) - \frac{π}{2} C (\frac{2}{π} \cdot 2 y)

Solution steps

\int_{2 y}^{2} 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)]_{2 y}^{2}

Compute the boundaries:

\frac{π}{2} C (\frac{2}{π} \cdot 2) - \frac{π}{2} C (\frac{2}{π} \cdot 2 y)

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