👉 Des math, or differential calculus, is a branch of mathematics that focuses on the study of change and motion. It explores how quantities change with respect to one another, particularly through the concepts of derivatives and integrals. Derivatives measure the rate at which a function changes at any given point, essentially answering how fast something is increasing or decreasing. Integrals, on the other hand, calculate the accumulation of quantities over a defined interval, such as finding the total distance traveled from a velocity function. Together, these tools enable us to model and analyze dynamic systems in fields like physics, engineering, economics, and biology, providing insights into the behavior of complex phenomena.
