📜 HISTORICAL BACKGROUND OF DIFFERENTIAL EQUATIONS 🌟 From Motion to Mathematical Equations Differential equations did not appear as an isolated branch of mathematics. They developed naturally from the study of motion, change, curves, mechanics, astronomy and physical phenomena . A differential equation relates an unknown function to one or more of its derivatives. Today, equations such as d y d x = f ( x , y ) \frac{dy}{dx}=f(x,y) are fundamental in mathematics, physics, engineering, economics and many other sciences. 🕰️ 1. The Beginning — Newton and Leibniz The history of differential equations is closely connected with the invention of calculus in the 17th century . 🔹 Isaac Newton (1642–1727) Newton developed his method of fluxions , thinking of quantities as things that flow or change with time . For example, if x x represents position, its rate of change can represent velocity: x ˙ = d x d t . \dot{x}=\frac{dx}{dt}. Newton applied these ideas to motion and mechanics . Hi...
