Cum se calculează Limit

Ce este 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.

Ghid pas cu pas

  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
