derivative of

y = - 2 x sin (x^{2})

- 2 (sin (x^{2}) + 2 x^{2} cos (x^{2}))

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = sin (x^{2})

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

\frac{d x}{d x} = 1

\frac{d}{d x} (sin (x^{2})) = cos (x^{2}) \cdot 2 x

= - 2 (1 \cdot sin (x^{2}) + cos (x^{2}) \cdot 2 xx)

Simplify

- 2 (1 \cdot sin (x^{2}) + cos (x^{2}) \cdot 2 xx) : - 2 (sin (x^{2}) + 2 x^{2} cos (x^{2}))

= - 2 (sin (x^{2}) + 2 x^{2} cos (x^{2}))
