Understanding This Calculator
Limit Definition
Evaluates the behavior of f(x) as x gets arbitrarily close to a value 'a'. Checks both left (x → a⁻) and right (x → a⁺) sides.
L = lim(x→a) f(x)
Example 1
f(x) = (x² - 1)/(x - 1) as x → 1
- Direct sub gives 0/0 (undefined).
- Simplify: (x-1)(x+1)/(x-1) = x+1
- Limit = 1 + 1 = 2
Example 2
f(x) = 1/x as x → ∞
- As x gets larger, 1/x approaches 0.
How to Use
- Enter the function f(x).
- Enter the value x approaches.
