Mathematical Foundation
The Normal Line Calculator is based on multivariable calculus principles. For a surface z = f(x, y), the normal line at a point (x₀, y₀, z₀) is perpendicular to the tangent plane and is defined by the parametric equations:
x = x₀ + fₓ(x₀, y₀)t, y = y₀ + fᵧ(x₀, y₀)t, z = z₀ - t
where:
- fₓ = ∂f/∂x, the partial derivative with respect to x.
- fᵧ = ∂f/∂y, the partial derivative with respect to y.
- z₀ = f(x₀, y₀), the function value at the point.
- t is the parameter.
The tool parses the input function, computes partial derivatives numerically (using a small delta), and constructs the normal line equations. This approach ensures alignment with peer-reviewed calculus methodologies, providing accurate and reliable results.
