integral of-cos(x^2)

\int - cos (x^{2}) d x

- \frac{π}{2} C (\frac{2}{π} x) + C

Solution steps

\int - cos (x^{2}) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int 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)

Add a constant to the solution

= - \frac{π}{2} C (\frac{2}{π} x) + C

\frac{d}{d x} (x 3 + 2 x^{2})

(\frac{1}{ln ( x )})^{^{'}}

(2 x + 3)^{^{'}}

\frac{d}{d x} (I n (x^{3} + x))

f (x) = 2 x^{2} + 7 x
