\frac{d}{d x} (- 4 cos (x) + x sin (x))

5 sin (x) + x cos (x)

Solution steps

\frac{d}{d x} (- 4 cos (x) + x sin (x))

Apply the Sum/Difference Rule:

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

= - \frac{d}{d x} (4 cos (x)) + \frac{d}{d x} (x sin (x))

\frac{d}{d x} (4 cos (x)) = - 4 sin (x)

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

= - (- 4 sin (x)) + sin (x) + x cos (x)

Simplify

= 5 sin (x) + x cos (x)

\int_{0}^{3} (3 - 2 x + x^{2}) d x

x \to 4 lim (6 x + ∣ x - 4 ∣)

x \to - \infty lim (x \cdot (- 1))

x ln (2 x) - x

f (x) = x^{2} + 3 x - 2
