\frac{d}{d x} (cos (0.5 x))

- sin (0.5 x) \cdot 0.5

Solution steps

\frac{d}{d x} (cos (0.5 x))

Apply the chain rule:

- sin (0.5 x) \frac{d}{d x} (0.5 x)

= - sin (0.5 x) \frac{d}{d x} (0.5 x)

\frac{d}{d x} (0.5 x) = 0.5

= - sin (0.5 x) \cdot 0.5

y^{^{'''}} - 9 y^{^{''}} + 15 y^{^{'}} + 25 y = 0

\frac{\partial}{\partial x} (\frac{x}{v})

x \to 8 + lim (\frac{∣ x - 8 ∣}{x - 8})

\frac{d}{d x} (\frac{5 x ^{3} - 7}{x})

f (x) = 10 cos (30 x - 7)
