Calculus is a branch of mathematics that focuses on rates of change and accumulation. It is used in various fields such as physics, engineering, economics, and more. Here are some fundamental concepts of calculus:
Derivatives: The derivative of a function measures its rate of change at a particular point. It is often used to find the slope of a curve or the velocity of an object.
Integrals: The integral of a function represents the area under the curve of the function. It is used to find the total amount of something over a period of time.
Limits: Limits are used to describe the behavior of a function as the input approaches a particular value.

Key Concepts
- Derivative: The derivative of a function ( f(x) ) with respect to ( x ) is denoted as ( f'(x) ) or ( \frac{df}{dx} ).
- Integral: The integral of a function ( f(x) ) with respect to ( x ) is denoted as ( \int f(x) dx ).
- Limit: The limit of a function ( f(x) ) as ( x ) approaches ( a ) is denoted as ( \lim_{{x \to a}} f(x) ).
Applications
Calculus is widely used in various fields:
- Physics: To calculate the velocity and acceleration of objects.
- Engineering: To design and analyze structures and systems.
- Economics: To model market behavior and predict trends.
