\frac{d}{d x} (\frac{3}{tan ( x )})

- 3 csc^{2} (x)

Solution steps

\frac{d}{d x} (\frac{3}{tan ( x )})

Simplify

\frac{3}{tan ( x )} : 3 cot (x)

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

Take the constant out:

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

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

Apply the common derivative:

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

= 3 (- csc^{2} (x))

Simplify

= - 3 csc^{2} (x)
