What is Calculus?

Calculus is a field of mathematics that studies change and motion. It is a powerful tool used to model, analyze, and solve many problems in science, engineering, and other fields.

Calculus has two main branches: differential calculus and integral calculus. Differential calculus is concerned with the rates at which things change, and it is used to calculate the derivative of a function, which measures the function’s pace of change at a particular location. Integral calculus is concerned with the accumulation of quantities and is used to calculate the integral of a process, which measures the area under the function’s curve.

Calculus is a highly theoretical and abstract discipline that involves modelling and solving issues using mathematical concepts such as limits, derivatives, and integrals. It is a significant branch of mathematics frequently used in various domains, such as physics, engineering, economics, and others.

The study of integrals and their properties is known as integral calculus. It is helpful for:

Determining f from f’ (i.e. from its derivative). If a function, say, f, may be defined in any given interval, then f’ is defined in that interval.

For any function, we are computing the area under a curve.

Calculus is also employed in areas as diverse as space flight, analyzing how pharmaceuticals interact with the body and even building safer constructions. If you understand the history of calculus and what it is supposed to perform and measure, you will know why it is essential in so many fields.
