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

- sin (x t) t

Solution steps

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

Treat

t

as a constant

Apply the chain rule:

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

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

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

= - sin (x t) t

x \to 0.5 lim (f (x))

\int_{1}^{5} \frac{2}{x ^{3}} d x

\frac{d}{d x} (arctan (x - 1))

\frac{d}{d x} (\frac{5}{e ^{x} + x})

x \to 1 + lim ((x - 3)^{2})
