Final answer:
Calculus is the branch of mathematics that deals with the study of change. It includes concepts such as limits, derivatives, integrals, and infinite series. These concepts are used in various disciplines to solve real-world problems.
Step-by-step explanation:
Calculus is the branch of mathematics that deals with the study of change. It includes the concepts of limits, derivatives, integrals, and infinite series. These concepts are used to solve problems in various disciplines, such as engineering, physics, and economics.
Differential calculus focuses on the rate of change of a function, while integral calculus deals with finding the area under a curve. Multivariable calculus extends these concepts to functions with multiple variables.
