Calculus is a branch of mathematics focused on understanding change and motion through two main concepts: differentiation and integration. Here’s a brief overview:
1. Differentiation
Differentiation deals with finding the derivative of a function, which measures how a function changes as its input changes. Key concepts include:
-
Derivative: Represents the rate of change of a function at a given point. For example, if f(x)f(x)f(x) is the position of an object over time, f′(x)f'(x)f′(x) (the derivative) gives the object's velocity.
-
Applications:
- Finding slopes of tangent lines.
- Determining maximum and minimum values (optimization problems).
- Analyzing motion (velocity and acceleration).
2. Integration
Integration is the process of finding the integral of a function, which can be thought of as the accumulation of quantities. Key concepts include:
-
Integral: Represents the area under a curve on a graph. For example, if f(x)f(x)f(x) represents velocity, the integral gives the total displacement over a time interval.
-
Applications:
- Calculating areas and volumes.
- Solving problems involving accumulation (e.g., total distance traveled).
- Finding the average value of a function over an interval.
Fundamental Theorem of Calculus
This theorem links differentiation and integration, stating that:
- If FFF is an antiderivative of fff, then: ∫abf(x) dx=F(b)−F(a)\int_a^b f(x) \, dx = F(b) - F(a) This shows how to compute the integral of a function using its antiderivative.
