👉 Ordinary Differential Calculus (ODC) is a branch of mathematics that deals with functions whose rates of change and slopes are studied. It focuses on understanding how functions change as their inputs vary, using concepts like derivatives to measure instantaneous rates of change and accumulation (integrals) to find areas under curves or total changes over intervals. ODC is fundamental for modeling dynamic systems in physics, engineering, economics, and biology, providing tools to analyze motion, optimize processes, and predict outcomes based on rates of change. Unlike Integral Calculus, which integrates to find total accumulation, ODC emphasizes local behavior—how a function behaves at a single point or over infinitesimally small intervals—and is crucial for understanding phenomena like velocity, acceleration, and growth rates in real-world applications.
