The Formal Theorem

x - f/f'

Analytical Intuition.

Newton-Raphson is the Linear Hunter. Finding roots by using the tangent line to predict the zero. Quadratic convergence: correct digits double with every step. Engine of scientific calculators.
CAUTION

Institutional Warning.

Tangent can send you flying if function is too flat. Good starting guess is key.

Academic Inquiries.

01

When does it fail?

If f' is zero or function is non-differentiable at the root.
