About Limits

A limit describes the value a function approaches as the input approaches a certain value.

Note: Full limit calculation requires advanced mathematical computation.

About This Calculator

Use the limit calculator when you want faster calculations with a clear method behind every result.

Evaluate function behavior near points and infinity to resolve continuity questions and calculus setup steps.

If your workflow expands, pair this calculator with Derivative Calculator and Integral Calculator to cross-check assumptions and build a stronger analysis chain.

Formula

Limit definition: lim[x->a] f(x) = L when f(x) approaches L as x approaches a.

Example Calculation

The worked example below demonstrates how the input fields translate into the final output. Use it as a quick validation pass before entering your own numbers.

  • expression: (x^2 - 1)/(x - 1)
  • approachValue: 1

Explanation of Results

Result Interpretation

After simplification to x + 1 (for x != 1), the expression approaches 2 as x approaches 1.

FAQ

Why can substitution fail for some limits?

Direct substitution can produce indeterminate forms like 0/0, which require algebraic or analytical simplification.

What is a one-sided limit?

It is the function behavior approaching a point from only the left or right direction.
