L Hospital Calculator

L’Hospital’s Rule Calculator

Calculating limits is a fundamental part of calculus, but certain forms can be tricky. Expressions like 0/0 or ∞/∞ are called indeterminate forms because the limit cannot be determined by simple substitution.

L’Hospital’s Rule is a powerful method that simplifies these problems by taking the derivatives of the numerator and denominator. The L’Hospital’s Rule Calculator makes this process effortless. It allows students, teachers, and mathematicians to quickly evaluate limits with accurate results.


What Is the L’Hospital’s Rule Calculator?

The L’Hospital’s Rule Calculator is an interactive online tool that:

  • Evaluates limits of the form 0/0 or ∞/∞
  • Calculates the limit after applying L’Hospital’s Rule
  • Shows the original limit expression, the derivative expression, and the final limit result
  • Helps users understand how derivatives simplify indeterminate forms

This tool is ideal for students learning calculus, educators, and anyone needing fast limit calculations.


How to Use the L’Hospital’s Rule Calculator

Step 1: Select the Indeterminate Form

Choose between 0/0 or ∞/∞, depending on the limit you are evaluating.

Step 2: Enter the Numerator Function f(x)

Type the numerator of your function. For example:
sin(x) or x^2 - 4

Step 3: Enter the Denominator Function g(x)

Type the denominator of your function. For example:
x or x - 2

Step 4: Specify the Limit Point

Enter the value x approaches, e.g., 0, 2, or any real number.

Step 5: Enter Derivatives

Input the derivative of the numerator f’(x) and the derivative of the denominator g’(x). For example:

  • f’(x) = cos(x)
  • g’(x) = 1

Step 6: Click “Calculate”

The calculator will show:

  • The original limit expression
  • The limit expression after L’Hospital’s Rule
  • The final limit result

Example Calculation

Problem: Evaluate the limit:limx0sin(x)x\lim_{x \to 0} \frac{\sin(x)}{x}x→0lim​xsin(x)​

Step 1: Identify the form → 0/0
Step 2: Numerator f(x) = sin(x)
Step 3: Denominator g(x) = x
Step 4: Limit point = 0
Step 5: Derivatives → f’(x) = cos(x), g’(x) = 1

Result:limx0sin(x)x=cos(0)1=1\lim_{x \to 0} \frac{\sin(x)}{x} = \frac{\cos(0)}{1} = 1x→0lim​xsin(x)​=1cos(0)​=1

Tips for Using L’Hospital’s Rule

  • Ensure the function is continuous and differentiable near the limit point
  • Only use the rule for indeterminate forms: 0/0 or ∞/∞
  • If the first application still gives an indeterminate form, apply the rule again
  • Double-check your derivatives for accuracy
