Derivative vs. Integral: Know the Difference
By Shumaila Saeed || Updated on December 26, 2023
Derivative measures the rate of change of a function, while an integral computes the area under the curve of a function.
Key Differences
A derivative, in calculus, is a measure of how a function changes as its input changes, essentially representing the rate of change or slope of the function at a given point. An integral, on the other hand, is a mathematical concept that represents the accumulation of quantities, often visualized as the area under a curve of a function over an interval. Both concepts are fundamental in calculus, but they serve distinct purposes.

The derivative of a function at a point gives the instantaneous rate of change of the function at that point, akin to finding the velocity of an object in motion at a specific moment. Conversely, the integral of a function over an interval calculates the total accumulation, similar to determining the total distance traveled by an object over a period. While derivatives break functions down to understand instantaneous changes, integrals accumulate these changes over intervals.

Derivatives are used to find local behaviors of functions, like maxima, minima, and points of inflection, which are crucial in fields like physics and engineering. Integrals, in contrast, are used to calculate quantities like area, volume, and total growth, playing a vital role in applications ranging from area calculation to probability. Both are tools for understanding different aspects of functions and their behaviors.

In practical terms, when a scientist calculates the derivative of a position function, they obtain velocity, showcasing how fast the position is changing at any moment. When they compute the integral of a velocity function, they get the total change in position, or displacement, over a time interval. Derivatives and integrals, though inverse operations, are both necessary for a comprehensive understanding of dynamic systems.

Integral
(mathematics) A definite integral: the result of the application of such an operation onto a function and a suitable subset of the function's domain: either a number or positive or negative infinity. In the former case, the integral is said to be finite or to converge; in the latter, the integral is said to diverge. In notation, the domain of integration is indicated either below the sign, or, if it is an interval, with its endpoints as sub- and super-scripts, and the function being integrated forming part of the integrand (or, generally, differential form) appearing in front of the integral sign.
