\frac{d}{d x} (\frac{x ^{2}}{sin ( a x )})

Vereinfache

\frac{x ^{2}}{sin ( a x )} : x^{2} csc (a x)

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

Wende die Produktregel an:

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

f = x^{2}, g = csc (a x)

= \frac{d}{d x} (x^{2}) csc (a x) + \frac{d}{d x} (csc (a x)) x^{2}

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

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

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

Vereinfache

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