Differential Calculus focuses on understanding how things change. It involves finding the rate of change of a function, which is represented by the derivative. For example, if you want to know how fast a car is moving at a specific moment, you would use differential calculus to calculate its speed based on its position over time. Integral Calculus, on the other hand, deals with accumulation and area. It helps us find the total quantity when we know the rate of change. For instance, if you want to determine the total distance traveled by the car over a period, you would use integral calculus to sum up all the small distances covered during that time.
