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

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

Solution steps

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

Take the constant out:

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

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

Apply the Product Rule:

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

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

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

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

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

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

Simplify

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

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

f (x) = 4 x - x^{2}, (1, 3)

\int - (1 - ln (x)) d x

\int \frac{x}{3} d x

x \to \infty lim (2 x^{2} - 1)

y^{^{'}} = y (x y^{3} + 1)
