    Example: TI-BASIC Program for Numerical Differentiation

    Below is a TI-BASIC code snippet demonstrating a central difference method for approximating derivatives. This program calculates the derivative of a user-defined function at a specified point using a small step size (`h`).

    ```html

    Program: NUMDERIV
    
// Approximates f'(x) using central difference method
    
// Syntax: NUMDERIV(f(x), x, h, x₀)
    
Prompt "Enter function f(x):", Str1
    
Prompt "Enter variable x:", Str2
    
Prompt "Enter step size h:", h
    
Prompt "Enter point x₀:", x₀
    // Convert string to function (simplified for demo)
    
Define f(x) = eval(Str1)
    // Central difference formula: f'(x₀) ≈ [f(x₀ + h) - f(x₀ - h)] / (2h)
    
deriv ≈ (f(x₀ + h) - f(x₀ - h)) / (2h)
    Disp "Derivative at x = " + x₀ + ": " + deriv
    ```

    Key Components:

  • `eval()`: Parses the user-input function string (e.g., `"x² + 3x + 2"`).
  • Central difference: Reduces truncation error compared to forward/backward differences.
  • Prompt/Display: Interacts with the user for inputs and outputs.

    • Applications:

  • Solving optimization problems in economics.
  • Modeling rates of change in physics (e.g., velocity from position).
  • Validating analytical derivatives in calculus courses.
