limit as x approaches infinity of x-3x^2

Lösung

x \to \infty lim (x - 3 x^{2})

- \infty

Schritte zur Lösung

x \to \infty lim (x - 3 x^{2})

Wende die Unendlichkeitseigenschaft an:

x \to \pm \infty lim (a x^{n} + \dots + b x + c) = - \infty, a < 0,

n is even

a = - 3, n = 2

= - \infty

x \to \frac{x}{2} lim (3 sec (x) - 3 tan (x))

x \to 3 lim (\frac{x ^{2} + 40 - 7}{x - 3})

x \to \frac{π}{2} lim (\frac{sin ( x )}{cos ( x )})

x \to π lim (\frac{sin ( x )}{2 + cos ( x )})

x \to - 1 lim (6 x^{3} - 7 x + 12)
