2. Specify Limits: Enter the lower limit (a) and upper limit (b) of the interval.
3. Choose Subintervals: Input the number of subintervals (n). A higher n (e.g., 1000) improves accuracy but increases computation time.
4. Calculate: Click the "Calculate" button to view the arc length.

Ensure the function is differentiable over [a, b] and that n is a positive integer. Invalid inputs or non-differentiable functions may produce errors.

When and Why You Should Use the Arc Length Calculator

The Arc Length Calculator is ideal for scenarios requiring the measurement of a curve’s length. Use it when:

This tool is valuable for quick computations, verifying manual calculations, or exploring the behavior of curves in various applications.

Purpose of the Arc Length Calculator

The primary purpose of the Arc Length Calculator is to provide a user-friendly, scientifically accurate tool for computing the arc length of a curve defined by a function f(x). Using numerical integration, it approximates the integral of the arc length formula, ensuring reliable results based on established mathematical principles. The calculator serves as an educational resource, a practical tool for professionals, and a means to explore curve properties, making complex computations accessible to all users.

Understanding Arc Length

The arc length of a curve y = f(x) from x = a to x = b is given by the formula:

L = ∫(a to b) √(1 + [f'(x)]²) dx,

where f'(x) is the derivative of f(x). Since this integral is often difficult to compute analytically, numerical methods like the Trapezoidal Rule are used to approximate it. The Arc Length Calculator implements this approach, dividing the interval [a, b] into n subintervals and summing the contributions of small segments. For more details, refer to Arc Length on Wikipedia.
