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

- x^{2} sin (x) + 4 x cos (x) + 2 sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

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

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

Simplify

2 (sin (x) + x cos (x)) - x^{2} sin (x) + 2 x cos (x) : - x^{2} sin (x) + 4 x cos (x) + 2 sin (x)

= - x^{2} sin (x) + 4 x cos (x) + 2 sin (x)

x \to \infty lim (3 \cdot x)

\int \frac{17}{x ln ( 3 x )} d x

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

4 x (3 - 2 x)^{5}, at x = 2

\int \frac{x ^{2} - a ^{2}}{x ^{4}} d x
