Guide to Using the Limits Calculator

This step-by-step guide will walk you through how to effectively use the Limits Calculator by filling in the necessary input fields and understanding the output results.

Step 1: Enter the x Value

Begin by entering the x value in the designated input field. This is the point at which you want to evaluate the limit. This field requires a numerical value, and it is essential for calculating the limits.

Step 2: Choose the Approach Direction

Select the Approach Direction from the provided options. You can choose either “From Left (x⁻)” or “From Right (x⁺)” to specify how the x value will be approached. This choice is crucial for understanding the behavior of the function near the specified x value.

Step 3: Determine the Step Size

Enter the Step Size to define increments toward the x value. Ensure the step size is a number between 0.0001 and 1, inclusive. A smaller step size results in more precise limit calculations, but it may also increase computational effort.

Step 4: Select the Function

Choose the Select Function option from the dropdown list. Available functions include “1/x”, “sin(x)/x”, “(x²-1)/(x-1)”, and “√x”. Selecting the appropriate function is necessary for evaluating the correct limit at the given x value.

Reviewing the Results

  • Limit Value: The calculated limit of the selected function at the specified x value and approach direction. It is displayed up to six decimal places.
  • Convergence Status: A numerical indication of whether the limit is convergent at the chosen approach, where 0 implies divergence and 1 implies convergence.
  • Left-hand Limit: The limit of the function as x approaches from the left. This value is also given to six decimal places for precision.
  • Right-hand Limit: The limit of the function as x approaches from the right. Like the Left-hand Limit, this provides a detailed view of the function’s tendency.

By following these steps, you can efficiently use the Limits Calculator to determine the behavior of different mathematical functions as they approach specific points. Understanding these results helps in analyzing function continuity and identifying potential discontinuities.
