Limit - Qurak function reference

Computes the limit of an expression as a variable approaches a value.

Uavhengig kontrollerbar: et svar for denne funksjonen utledes på nytt via en annen rute og sammenlignes - arbeidsbenken og verify-verktøyet gjør dette automatisk, så et galt svar fanges opp i stedet for å stoles på. Historikk →

Verifiserte eksemplerLimit[(1 + 1/n)^n, n -> Infinity] → E Limit[(Sin[x] - x)/x^3, x -> 0] → -1/6 Limit[x/(x + Sqrt[x]), x -> Infinity] → 1 Limit[(3 x^(3/2) + x)/(2 x^(3/2) - 1), x -> Infinity] → 3/2 Limit[(a x + b)/(c x + d), x -> Infinity] → a/c Limit[(x + Sqrt[x])/(x - Sqrt[x]), x -> 0] → -1 Limit[1/x^2, x -> 0] → Infinity Limit[1/x^3, x -> 0] → Indeterminate Limit[1/x, x -> 0, Direction -> "FromAbove"] → InfinityAlternativer
