Limit describes value function approaches as input approaches some value: lim(x→a) f(x) = L. Foundation of calculus.
Panduan Langkah demi Langkah
- 1Input function and point
- 2Calculate limit by substitution, factoring, L'Hôpital's rule, or numeric approximation
- 3Results show limit value
Contoh Terpecahkan
Masukan
lim(x→2) (x²-4)/(x-2)
Hasil
= lim(x→2) (x+2) = 4 (factor to remove discontinuity)
Kesalahan Umum yang Harus Dihindari
- ✕Direct substitution when undefined (0/0)
- ✕Not checking left and right limits
Pertanyaan yang sering diajukan
