Schritte zur Lösung

Steigung der Normalen in

(2, 1) : m = \frac{- X ^{5} + 4 X ^{3} - X ^{2} - 3 X + 2}{X - 2}

Finde die Steigung von

Y = (3 - X^{2}) (X^{3} - X + 1) : m_{y} = - 5 X^{4} + 12 X^{2} - 2 X - 3

Berechne die Steigung der Normalen:

m = - \frac{1}{- 5 X ^{4} + 12 X ^{2} - 2 X - 3}

Löse

\frac{- X ^{5} + 4 X ^{3} - X ^{2} - 3 X + 2}{X - 2} = - \frac{1}{- 5 X ^{4} + 12 X ^{2} - 2 X - 3} : X \approx 0.86915 \dots, X \approx - 1.79826 \dots, X \approx 1.65885 \dots, X \approx - 1.60832 \dots, X \approx 1.29476 \dots, X \approx - 1.08306 \dots, X \approx - 0.51928 \dots
