Newton's Method and Its Applications

The video introduces Newton's Method, a numerical algorithm for finding roots of functions. It explains the challenges of solving polynomial equations algebraically and presents Newton's Method as a solution. The method involves iterating guesses to approximate roots, requiring the function's derivative. An example demonstrates the process, calculating a root to four decimal places. The video concludes with a preview of future topics in calculus.
