derivative of

\frac{3 x}{8 - cot ( x )}

\frac{3 ( 8 - cot ( x ) - x csc ^{2} ( x ) )}{( 8 - cot ( x ) ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{3 x}{8 - cot ( x )})

Take the constant out:

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

= 3 \frac{d}{d x} (\frac{x}{8 - cot ( x )})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= 3 \cdot \frac{\frac{d x}{d x} ( 8 - cot ( x ) ) - \frac{d}{d x} ( 8 - cot ( x ) ) x}{( 8 - cot ( x ) ) ^{2}}

\frac{d x}{d x} = 1

\frac{d}{d x} (8 - cot (x)) = csc^{2} (x)

= 3 \cdot \frac{1 \cdot ( 8 - cot ( x ) ) - csc ^{2} ( x ) x}{( 8 - cot ( x ) ) ^{2}}

Simplify

3 \cdot \frac{1 \cdot ( 8 - cot ( x ) ) - csc ^{2} ( x ) x}{( 8 - cot ( x ) ) ^{2}} : \frac{3 ( 8 - cot ( x ) - x csc ^{2} ( x ) )}{( 8 - cot ( x ) ) ^{2}}

= \frac{3 ( 8 - cot ( x ) - x csc ^{2} ( x ) )}{( 8 - cot ( x ) ) ^{2}}
