\frac{d}{d x} (3 arcsin (\frac{x}{2}))

\frac{3}{4 - x ^{2}}

Solution steps

\frac{d}{d x} (3 arcsin (\frac{x}{2}))

Take the constant out:

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

= 3 \frac{d}{d x} (arcsin (\frac{x}{2}))

Apply the chain rule:

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

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

\frac{d}{d x} (\frac{x}{2}) = \frac{1}{2}

= 3 \cdot \frac{1}{1 - ( \frac{x}{2} ) ^{2}} \cdot \frac{1}{2}

Simplify

3 \cdot \frac{1}{1 - ( \frac{x}{2} ) ^{2}} \cdot \frac{1}{2} : \frac{3}{4 - x ^{2}}

= \frac{3}{4 - x ^{2}}
