微积分

the branch of mathematics that comprises differentials and integrals

What is "calculus"?

Calculus is a branch of mathematics that deals with change and motion, focusing on concepts like limits, derivatives, and integrals. It helps to understand how things change over time or how they accumulate, such as in physics or economics. Calculus is essential for solving problems involving rates of change, areas under curves, and optimization.
