In mathematics, the term "conjugate" can refer to different concepts depending on the context, particularly in complex numbers and algebraic expressions.
Equating coefficients is a mathematical technique often used to solve polynomial equations or to find relationships between different algebraic expressions. This method is particularly useful in situations where you have two polynomials that are set equal to each other, and you want to find values for their coefficients or variables. Here's how it generally works: 1. **Setup Equations**: Start with two polynomials that are equal to each other.
A worm's-eye view is a perspective used in photography, art, and visual storytelling that depicts a scene from a low angle, as if the viewer were at the level of a worm looking up. This perspective can emphasize the height of objects, such as buildings or trees, creating a sense of grandeur or immensity. It often conveys feelings of vulnerability or insignificance, as the viewer sees the world from a position that is usually not encountered in everyday life.
Factorization is the process of breaking down an expression, number, or polynomial into a product of its factors. Factors are numbers or expressions that can be multiplied together to obtain the original number or expression. Factorization is a fundamental concept in mathematics, used in various areas such as arithmetic, algebra, and number theory.
The term "formula" can have different meanings depending on the context in which it is used: 1. **Mathematics and Science**: In mathematics and science, a formula is a concise way of expressing information symbolically. It consists of mathematical symbols and numbers that represent a relationship or rule.
A linear equation is a mathematical equation that represents a straight line when graphed on a coordinate plane. It typically takes the form: \[ ax + by + c = 0 \] or in slope-intercept form: \[ y = mx + b \] where: - \( x \) and \( y \) are the variables. - \( a \), \( b \), and \( c \) are constants (with \( a \) and \( b \) not both zero).
Solving quadratic equations using continued fractions is a method linked to the approximation of the solutions of these equations through the use of continued fractions. Quadratic equations typically take the form: \[ ax^2 + bx + c = 0 \] where \(a\), \(b\), and \(c\) are coefficients, and \(x\) is the variable we want to solve for.
A relation \( R \) on a set is called a transitive relation if, for all elements \( a, b, c \) in that set, whenever \( a \) is related to \( b \) (denoted \( aRb \)) and \( b \) is related to \( c \) (denoted \( bRc \)), then \( a \) must also be related to \( c \) (denoted \( aRc \)).
Two-element Boolean algebra, also known as Boolean algebra of two values, is a mathematical structure that deals with binary variables that can take on one of two values: typically represented as 0 and 1. This framework is foundational to digital logic and computer science.
In mathematics, the term "sign" refers to the indication of whether a number is positive, negative, or zero. It is typically represented using the following symbols: - Positive numbers: Represented by a plus sign (+) or no sign at all (e.g., +5 or 5). - Negative numbers: Represented by a minus sign (−) (e.g., −3). - Zero: The number 0 is neutral and does not carry a sign.
In mathematics, equality is a fundamental relationship that asserts that two expressions represent the same value or entity. It is typically denoted by the equality symbol "=". When we say that two things are equal, we mean that they have the same mathematical value or that they are identical in a specific context.
Multiplication is one of the four fundamental arithmetic operations in mathematics, alongside addition, subtraction, and division. It involves combining equal groups of items to find the total number of items. In simpler terms, multiplication can be thought of as repeated addition.
Euclidean plane geometry is a branch of mathematics that studies the properties and relationships of points, lines, angles, surfaces, and shapes in a two-dimensional plane. It is named after the ancient Greek mathematician Euclid, who is often referred to as the "father of geometry" due to his influential work, "Elements," which systematically presented the principles and proofs of geometry.
Orthogonality is a concept used in various fields, primarily in mathematics, statistics, and computer science, which describes the idea of two vectors being perpendicular to each other in a specific space. In the context of Euclidean space, two vectors are said to be orthogonal if their dot product is zero.
As of my last knowledge update in October 2021, there is no widely recognized figure or concept by the name "Ivan Rayment." It's possible that it could refer to a private individual or a term that has gained significance after my last update.
DeCSS haiku refers to a poem that captures the essence or themes related to DeCSS, which is a program that allows users to decrypt DVDs. DeCSS became prominent in legal battles over copyright and digital rights. The haiku format, which consists of three lines with a syllable pattern of 5-7-5, can express the complexities and controversies surrounding DeCSS and digital rights.
A "portable hole" is a fictional object commonly found in fantasy role-playing games like Dungeons & Dragons (D&D) and in various forms of media, particularly cartoons and comic strips. It is typically depicted as a circular piece of fabric or material that, when laid flat on a surface, creates an extra-dimensional space or a hole that can be used to store items or, in some cases, serve as a means of travel.
Apollonian circles are a fascinating concept in geometry associated with the problem of Apollonius, which involves finding circles that are tangent to three given circles in a plane. The study of these circles reveals insights into various geometric properties, including tangency, curvature, and configuration. In more detail: 1. **Apollonius' Problem**: The classical problem, attributed to Apollonius of Perga, asks for the construction of a circle that is tangent to three given circles.
A bicentric polygon is a type of polygon that possesses both a circumcircle and an incircle. A circumcircle is a circle that passes through all the vertices of the polygon, while an incircle is a circle that is tangent to each side of the polygon. For a polygon to be classified as bicentric, it must meet specific criteria: 1. **Circumcircle**: All the vertices of the polygon lie on a single circle.
Birkhoff's axioms refer to a set of axioms introduced by mathematician George David Birkhoff in the context of defining the concept of a "relation" in mathematics, particularly pertaining to the fields of algebra and geometry. However, it is important to clarify that Birkhoff is perhaps best known for his work in lattice theory and the foundations of geometry.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
