Limits

A limit describes the value a function approaches as the input approaches a particular point. Fundamental in calculus, derivatives, and integrals. Key Concepts: Notation: lim⁡x→af(x)=L\lim_{x \to a} f(x) = Lx→alim​f(x)=L…

Determinants

Determinant is a scalar value derived from a square matrix. It is used to determine invertibility, solutions of equations, and area/volume calculations. Key Concepts: Determinant of 2×2 matrix: ∣A∣=∣abcd∣=ad−bc|A| =…

Matrices

A matrix is a rectangular array of numbers arranged in rows and columns. Used in linear algebra, computer graphics, engineering, and statistics. Key Concepts: Types of Matrices: Row, Column, Square,…

Relations & Functions

Relations and functions describe connections between sets. Functions are a special type of relation with unique mapping. Relations: A relation R from set A to B is a subset of…

Set Theory

Description:Set theory is the study of collections of objects called sets. It forms the foundation of modern mathematics and is widely used in logic, computer science, and probability. Key Concepts:…

Sequential Circuits

A Sequential Circuit is a type of digital circuit where the output depends on both the current inputs and the past history of inputs. Unlike combinational circuits, sequential circuits have…

Combinational Circuits

A Combinational Circuit is a type of digital circuit where the output depends only on the current inputs, not on any previous inputs or history. There is no memory element…

Boolean Algebra

Boolean Algebra is a mathematical system for analyzing and simplifying digital logic circuits. It is named after George Boole, who developed a formal system to work with binary variables (0…

Logic Gates

Logic gates are the fundamental building blocks of digital electronics. They perform logical operations on one or more binary inputs (0 or 1) to produce a single binary output (0…

Number Systems

A number system is a way to represent numbers using a consistent set of symbols. In digital electronics, numbers are represented in different bases because digital circuits only understand binary…
