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

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

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

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

Simplify

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

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

\frac{\partial}{\partial x} (x y^{7} + x^{4} + y^{8})

(- 5, 2), (3, - 7)

\int \frac{3 x + 2}{x ^{2} + 1} d x

y = x^{3} - 7 x, y = 9 x

\frac{t}{5}
