\frac{d}{d x} (6 x cos (x^{2}))

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

Solution steps

\frac{d}{d x} (6 x cos (x^{2}))

Take the constant out:

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

= 6 \frac{d}{d x} (x cos (x^{2}))

Apply the Product Rule:

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

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

= 6 (\frac{d x}{d x} cos (x^{2}) + \frac{d}{d x} (cos (x^{2})) x)

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

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

= 6 (1 \cdot cos (x^{2}) + (- sin (x^{2}) \cdot 2 x) x)

Simplify

6 (1 \cdot cos (x^{2}) + (- sin (x^{2}) \cdot 2 x) x) : 6 (cos (x^{2}) - 2 x^{2} sin (x^{2}))

= 6 (cos (x^{2}) - 2 x^{2} sin (x^{2}))

\int_{1}^{e} \frac{x ^{2} + 1}{x} d x

y^{^{''}} = - 25 y

\int_{0}^{1} (x^{2} - x) d x

\int \frac{1}{6 - x} d x

\int 1 + x^{4} d x
