derivative of arccos((10/x))

Solution

\frac{d}{d x} (arccos (\frac{10}{x}))

Solution

\frac{10}{x x ^{2} - 100}

Solution steps

\frac{d}{d x} (arccos (\frac{10}{x}))

Apply the chain rule:

- \frac{1}{1 - ( \frac{10}{x} ) ^{2}} \frac{d}{d x} (\frac{10}{x})

= - \frac{1}{1 - ( \frac{10}{x} ) ^{2}} \frac{d}{d x} (\frac{10}{x})

\frac{d}{d x} (\frac{10}{x}) = - \frac{10}{x ^{2}}

= - \frac{1}{1 - ( \frac{10}{x} ) ^{2}} (- \frac{10}{x ^{2}})

Simplify

- \frac{1}{1 - ( \frac{10}{x} ) ^{2}} (- \frac{10}{x ^{2}}) : \frac{10}{x x ^{2} - 100}

= \frac{10}{x x ^{2} - 100}
