derivative of

f (x) = - csc (x) cot (x)

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

Solution steps

\frac{d}{d x} (- csc (x) cot (x))

Take the constant out:

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

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = csc (x), g = cot (x)

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

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

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

= - ((- cot (x) csc (x)) cot (x) + (- csc^{2} (x)) csc (x))

Simplify

- ((- cot (x) csc (x)) cot (x) + (- csc^{2} (x)) csc (x)) : - csc (x) + 2 csc^{3} (x)

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