(\partial)/(\partial x)(cos(x^2))

\frac{\partial}{\partial x} (cos (x^{2}))

- sin (x^{2}) \cdot 2 x

Solution steps

\frac{\partial}{\partial x} (cos (x^{2}))

Apply the chain rule:

- sin (x^{2}) \frac{\partial}{\partial x} (x^{2})

= - sin (x^{2}) \frac{\partial}{\partial x} (x^{2})

\frac{\partial}{\partial x} (x^{2}) = 2 x

= - sin (x^{2}) \cdot 2 x
