derivative of ((a+bx^n/(a-bx^n))^m)

Lösung

\frac{d}{d x} ((\frac{a + b x ^{n}}{a - b x ^{n}})^{m})

\frac{2 abnm x ^{n - 1} ( a + b x ^{n} ) ^{m - 1}}{( a - b x ^{n} ) ^{m + 1}}

Schritte zur Lösung

\frac{d}{d x} ((\frac{a + b x ^{n}}{a - b x ^{n}})^{m})

Wende die Kettenregel an:

m (\frac{a + b x ^{n}}{a - b x ^{n}})^{m - 1} \frac{d}{d x} (\frac{a + b x ^{n}}{a - b x ^{n}})

= m (\frac{a + b x ^{n}}{a - b x ^{n}})^{m - 1} \frac{d}{d x} (\frac{a + b x ^{n}}{a - b x ^{n}})

\frac{d}{d x} (\frac{a + b x ^{n}}{a - b x ^{n}}) = \frac{2 abn x ^{n - 1}}{( a - b x ^{n} ) ^{2}}

= m (\frac{a + b x ^{n}}{a - b x ^{n}})^{m - 1} \frac{2 abn x ^{n - 1}}{( a - b x ^{n} ) ^{2}}

Vereinfache

m (\frac{a + b x ^{n}}{a - b x ^{n}})^{m - 1} \frac{2 abn x ^{n - 1}}{( a - b x ^{n} ) ^{2}} : \frac{2 abnm x ^{n - 1} ( a + b x ^{n} ) ^{m - 1}}{( a - b x ^{n} ) ^{m + 1}}

= \frac{2 abnm x ^{n - 1} ( a + b x ^{n} ) ^{m - 1}}{( a - b x ^{n} ) ^{m + 1}}
