Как да изчислим Limit

Какво е Limit?

A limit describes the value a function approaches as its input approaches a particular value. Limits are the rigorous foundation of calculus — they underpin the definitions of continuity, derivatives, and integrals. Our calculator uses numerical evaluation from both sides (left and right) to estimate limits for continuous functions.

Ръководство стъпка по стъпка

  1. 1lim(x→c) f(x) = L means f(x) gets arbitrarily close to L as x approaches c
  2. 2Left-hand limit (x→c⁻): approach from values less than c
  3. 3Right-hand limit (x→c⁺): approach from values greater than c
  4. 4A limit exists only if left and right limits agree
  5. 5Numerically: evaluate at x = c ± 10⁻⁸ and check if results agree to within 10⁻⁶

Worked Examples

Вход
lim(x→0) sin(x)/x
Резултат
1
Classic limit; indeterminate 0/0 — use L'Hôpital's rule
Вход
lim(x→1) (x²−1)/(x−1)
Резултат
2
Factor: (x+1)(x−1)/(x−1) = x+1 → 2 as x→1
Вход
lim(x→0) |x|/x
Резултат
Does not exist
Left limit = −1, right limit = +1
