tangent y=2x^2+x,(1,2)

Lösung

tangente von

y = 2 x^{2} + x, (1, 2)

Lösung

y = (22 + 5) x - 3 - 22 or y = (5 - 22) x - 3 + 22

Schritte zur Lösung

Steigung der Tangente an

(1, 2) : m = \frac{2 x ^{2} + x - 2}{x - 1}

Finde die Steigung von

y = 2 x^{2} + x : m = 4 x + 1

Löse

4 x + 1 = \frac{2 x ^{2} + x - 2}{x - 1} : x = \frac{2 + 2}{2}, x = \frac{2 - 2}{2}

Finde die Tangente an

x = \frac{2 + 2}{2} : y = (22 + 5) x - 3 - 22

Finde die Tangente an

x = \frac{2 - 2}{2} : y = (5 - 22) x - 3 + 22

y = (22 + 5) x - 3 - 22 or y = (5 - 22) x - 3 + 22
