derivative of

y = arccos (5 x)

- \frac{5}{1 - 25 x ^{2}}

Solution steps

\frac{d}{d x} (arccos (5 x))

Apply the chain rule:

- \frac{1}{1 - ( 5 x ) ^{2}} \frac{d}{d x} (5 x)

= - \frac{1}{1 - ( 5 x ) ^{2}} \frac{d}{d x} (5 x)

\frac{d}{d x} (5 x) = 5

= - \frac{1}{1 - ( 5 x ) ^{2}} \cdot 5

Simplify

- \frac{1}{1 - ( 5 x ) ^{2}} \cdot 5 : - \frac{5}{1 - 25 x ^{2}}

= - \frac{5}{1 - 25 x ^{2}}
