Overview of Calculus

A branch of mathematics that investigates continuous change, crucial for various scientific fields.
Comprises two main areas: Differential Calculus and Integral Calculus.

Differential Calculus

Concentrates on derivatives, which quantify how a function changes in response to small variations in input.
Derivative Definition:
- Indicates the rate of change of a function.
- Represents the slope of the tangent line to the function's graph.
Key Concepts:
- Function Notation: Often expressed as ( f(x) ).
- Limit: Essential for understanding derivatives.
- Derivative Notation: Denoted as ( f'(x) ) or ( \frac{dy}{dx} ).
Rules of Differentiation:
- Power Rule: ( \frac{d}{dx}(x^n) = nx^{n-1} ).
- Product Rule: ( (uv)' = u'v + uv' ).
- Quotient Rule: ( \left(\frac{u}{v}\right)' = \frac{u'v - uv'}{v^2} ).
- Chain Rule: ( (f(g(x)))' = f'(g(x))g'(x) ).

Integral Calculus

Centers on integrals, which represent accumulated quantities, such as areas under curves.
Integral Definition:
- Sums continuous data to calculate total quantities.
Key Concepts:
- Definite Integral: Calculates the area under the curve between specific limits ( a ) and ( b ).
- Indefinite Integral: Represents a collection of functions, expressed as ( \int f(x) , dx ).
Fundamental Theorem of Calculus:
- Links differentiation and integration through two key statements:
  - If ( F ) is an antiderivative of ( f ), then ( \int_a^b f(x) , dx = F(b) - F(a) ).
  - ( \frac{d}{dx} \int_a^x f(t) , dt = f(x) ).

Applications of Calculus

Essential in fields such as physics, engineering, economics, and biology.
Key applications include:
- Determining maximum and minimum values of functions.
- Analyzing kinematics and dynamic systems.
- Modeling real-world scenarios through mathematical frameworks.

Important Topics in Calculus

Limits and Continuity: Investigating function behavior at specific points or as inputs approach certain values.
Techniques of Integration:
- Employing methods like substitution, integration by parts, and trigonometric substitution to solve integrals.
Series and Sequences:
- Studying convergence and divergence to understand infinite series and their behaviors.
