\frac{d}{d x} (2 π x (cos (π x^{2})))

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

Solution steps

\frac{d}{d x} (2 π x (cos (π x^{2})))

Take the constant out:

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

= 2 π \frac{d}{d x} (x cos (π x^{2}))

Apply the Product Rule:

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

f = x, g = cos (π x^{2})

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

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

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

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

Simplify

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

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