derivative of

cos (\frac{x}{3})

- sin (\frac{x}{3}) \frac{1}{3}

Solution steps

\frac{d}{d x} (cos (\frac{x}{3}))

Apply the chain rule:

- sin (\frac{x}{3}) \frac{d}{d x} (\frac{x}{3})

= - sin (\frac{x}{3}) \frac{d}{d x} (\frac{x}{3})

\frac{d}{d x} (\frac{x}{3}) = \frac{1}{3}

= - sin (\frac{x}{3}) \frac{1}{3}

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

n = 4 \sum \infty \frac{1}{( n - 4 ) !}

\frac{d}{d t} (t^{2} + \frac{2 t}{t} - \frac{1}{t ^{2}})

\int \frac{12}{1 + x ^{2}} d x

\frac{d}{d θ} (- 10 sin (θ))
