## Key Differences

Derivatives focus on the instantaneous rate of change at any given point of a function, essentially determining how a function changes as its input changes. In contrast, integrals are used to calculate the total accumulation of quantities, which can be thought of as the area under a curve between two points on a graph.

Derivatives are fundamental in fields like physics and engineering, where changes in motion or rates are crucial, such as calculating velocity or acceleration from a position-time graph. On the other hand, integrals are key in processes involving total quantities, such as finding the total distance traveled given a velocity-time graph.

The process of finding a derivative is known as differentiation, which involves applying specific rules to a function to determine another function that predicts changes. Whereas, integration, the process of finding an integral, often requires summing infinite slices to find whole values, which can be more computationally intensive.

Applications of derivatives include optimization problems, where one needs to find maximum or minimum values, crucial in economics and logistics. Conversely, integrals are used extensively in probability to determine the likelihood of events, integral to statistics and risk assessment.
