derivative of

\frac{- cos ( x )}{sin ^{2} ( x )}

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

Solution steps

\frac{d}{d x} (\frac{- cos ( x )}{sin ^{2} ( x )})

Simplify

\frac{- cos ( x )}{sin ^{2} ( x )} : - cot (x) csc (x)

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

Take the constant out:

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

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

Apply the Product Rule:

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

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

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

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

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

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

Simplify

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

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

(lo g_{10} (x^{3} + 4))^{5}

\frac{1}{( x + 4 ) ^{3}}

f (t) = \frac{t ^{2} - 1}{t ^{2} + t - 2}

\frac{d}{d x} (9 x^{2} - 12 x + 20 a)

y = (x^{2} + 1) (\frac{x + 5 + 1}{x})
