\frac{d}{d x} (2 arccos (x))

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

Solution steps

\frac{d}{d x} (2 arccos (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d x} (arccos (x))

Apply the common derivative:

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

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

Simplify

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

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

x \to - 2 lim (4 x^{2} - 3)

f (x) = 2 - x^{2}

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

\frac{d}{d x} (3 x - ln (3 x + 1))

2 x, x
