Picard's Theorem: Existence and Uniqueness of Differential Equation Solutions
Picard's Theorem: Existence and Uniqueness of Differential Equation Solutions In mathematics, differential equations are fundamental tools for describing natural phenomena, physical laws, and economic models. But a crucial question arises: Does a given differential equation actually have a solution? And if so, is that solution unique? This is precisely the question that Picard's Theorem addresses. Picard's Theorem is a fundamental result that guarantees both the existence and uniqueness of solutions for a general first-order differential equation. In this post, we will explore what Picard's Theorem is, why it is important, and how it is applied. 📌 Table of Contents What is Picard's Theorem?
