Limit describes value function approaches as input approaches some value: lim(x→a) f(x) = L. Foundation of calculus.
Trin-for-trin guide
- 1Input function and point
- 2Calculate limit by substitution, factoring, L'Hôpital's rule, or numeric approximation
- 3Results show limit value
Løste eksempler
Input
lim(x→2) (x²-4)/(x-2)
Resultat
= lim(x→2) (x+2) = 4 (factor to remove discontinuity)
Almindelige fejl at undgå
- ✕Direct substitution when undefined (0/0)
- ✕Not checking left and right limits
Ofte stillede spørgsmål
