What+is++Trigonometry
Trigonometry is the branch of mathematics that studies relationships between sides and angles of triangles. It is used to determine unknown sides and angles using properties of right triangles and trigonometric functions like sine, cosine, and tangent. Trigonometry has applications in fields like navigation, surveying, engineering, and physics for solving problems involving calculations with circular functions.
Trigonometric Identities
Trigonometric identities are mathematical relationships that allow trigonometric expressions to be manipulated or simplified. Some common identities include the Pythagorean identities, the double-angle identities, the half-angle identities, and the sum and difference identities. These identities can be used to simplify complex trigonometric expressions and solve trigonometric equations.
Vertically+Opposite+Angles
Vertically opposite angles are two angles located on opposite sides of a vertical line. These two angles are always equal in measure because they are in the same relative position to the vertical line. Knowing that vertically opposite angles are congruent is useful for solving problems involving parallel lines cut by a transversal.
Types+of+Polynomials
Polynomials are expressions containing terms with variables raised to whole number powers. Monomials are single terms of polynomials containing one or more variables raised to whole number powers. Polynomial expressions contain two or more terms that are added or subtracted.
Adjacent+Angle
Two angles are adjacent if they share a common side or vertex. Adjacent angles are not considered vertical angles. When two angles are adjacent, their measures are not added together but considered separately.
Composite Numbers
Composite numbers are integers greater than 1 that can be made by multiplying two or more prime numbers. Examples of composite numbers include 4, 6, 8, 9, 10, 12, and so on. Most positive integers are composite numbers, while prime numbers are only divisible by 1 and themselves without any remainders.
Prime Numbers
Prime numbers are positive integers greater than 1 that are only divisible by 1 and themselves. They do not have any factors other than 1 and themselves. The first few prime numbers are 2, 3, 5, 7, 11, and 13.
Even Numbers
Even numbers are integers that are exactly divisible by 2 without leaving a remainder. Some key properties of even numbers are that they can be expressed as the sum of two equal addends, the last digit is always 0, 2, 4, 6, or 8, and when divided by two the result is always an integer. Even numbers also have the unique property that the sum of all digits in an even number is always even.

Hexadecimal Numbers
Hexadecimal is a base-16 numeral system that uses 16 distinct symbols (0-9 and A-F) to represent values. It is commonly used in computing and digital electronics to represent binary numbers in a more human-readable form. Hexadecimal numbers are often prefixed with "0x" to indicate they are represented in hexadecimal base.
Subtracting Fractions
To subtract fractions, find a common denominator and subtract the numerators. Change any mixed numbers to improper fractions first. Then rewrite the answer in simplest form.
Composite Numbers
Composite numbers are integers greater than 1 that can be made by multiplying two or more prime numbers. Most numbers are composite, as only prime numbers like 2, 3, 5, 7, etc. are not made by multiplying other numbers. Common examples of composite numbers include 4, 6, 8, 9, 12, and many larger integers.
Convert Fractions to Decimals
To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/2 equals 0.5 because 1 divided by 2 is 0.5. Common fractions like 1/2, 1/4 and 3/4 can be easily converted to decimals. More complex fractions may require calculating the division to several decimal places.
Asymptote
Asymptote is a mathematical term referring to a line that a graph approaches but never meets. A vertical asymptote occurs when the function approaches positive or negative infinity as the variable increases or decreases without bound. A horizontal asymptote is a horizontal line that a function approaches but does not meet as the variable increases or decreases without bound.
Precalculus Functions
Precalculus functions introduces the key concepts of functions including domain and range, types of functions such as polynomial, rational, exponential, and logarithmic functions. It explores the properties of functions including composition, inverses, and transformations. Students learn to analyze functions graphically and algebraically and how to apply functions to model real-world situations.
Rational Function
This document discusses rational functions. It covers asymptotes of rational functions, which are lines or curves that a rational function approaches but does not meet as the independent variable approaches infinity or a vertical asymptote. The document explains how to find vertical, horizontal and oblique asymptotes of rational functions by examining limits of the functions.
Spherical Coordinates
Spherical coordinates provide an alternative to Cartesian coordinates by representing the position of a point in three-dimensional space using three values: the radial distance from the origin, the polar angle measured from the positive z-axis, and the azimuthal angle measured in the xy-plane from the positive x-axis.
Plane Curve
A plane curve is a curve that lies in a plane. It is a geometric object used in branches of mathematics like calculus and complex analysis to study properties like curvature, arc length, and areas bounded by the curve. Plane curves include lines, circles, ellipses, parabolas, hyperbolas, spirals, and other shapes that can be described by a single equation involving x and y coordinates.
Translation Math
Translation math is a technique for translating between different mathematical systems or notations. It involves understanding how concepts relate or correspond between systems, like converting fractions to decimals or expressions in one system to an equivalent expression in another. The goal is to be able to accurately represent the same mathematical idea using different symbols or conventions while preserving meaning.
Introduction to Precalculus
Precalculus is a course that prepares students for calculus by covering topics such as functions, polynomials, trigonometry, logarithms, and exponentials. It builds on algebra skills and introduces more advanced concepts. The goal is to help students develop a strong foundation in mathematics before taking calculus.
multiplying fractions
To multiply fractions, multiply the numerators together and multiply the denominators together. For example, to multiply 1/2 and 3/4, multiply the numerators 1 x 3 to get 3, and multiply the denominators 2 x 4 to get 8. So 1/2 x 3/4 = 3/8.
Graphs of Circular Functions
Circular functions like sine and cosine are periodic, repeating their values over time. Their graphs take the form of smooth, repeating waves that oscillate between -1 and 1 as the independent variable increases. These graphs are useful in modeling real-world phenomena involving periodic motion or cycling values like tides, radio waves, and alternating current.
Applications+of+Radian+Measures
Radian measures are used to describe angles and rotations. They allow for easier calculations than degree measures in many applications involving circles and periodic phenomena. Some examples include describing the positions of objects orbiting in space, analyzing rotating machinery, and studying oscillations in physics.
Limits+and+Derivatives
Limits and derivatives are fundamental concepts in calculus that are used to find instantaneous rates of change and slopes of curves. A limit describes the value a function approaches as the input gets closer to a certain value, while a derivative measures the slope of the tangent line to a curve at a point and instantaneous rate of change of the function at that point. These concepts are building blocks for advanced calculus topics like optimization, differential equations, and integration.
Determinants
Determinants are mathematical expressions used to calculate the area or volume of geometric shapes. They are often represented as a number below and to the right of a matrix. Calculating determinants involves finding the sum of the products of entries across the main diagonal of a square matrix with appropriate sign changes for rows not on the main diagonal.
Matrices
Matrices are two-dimensional tables of numbers or expressions arranged in rows and columns. They are useful for representing linear transformations and solving systems of linear equations. Matrices can be added, subtracted, and multiplied according to specific rules to perform operations on multiple values simultaneously.
Continuity+and+Differentiability
Continuity and differentiability are key concepts in calculus. A function is continuous if its value can change smoothly at every point in its domain. A function is differentiable if its derivative exists at every point, meaning the graph has a tangent line and its slope changes gradually. Together, continuity and differentiability allow functions to model real-world phenomena through smooth, unbroken curves and slopes.
Sequences+and+Series
Sequences and series are mathematical concepts involving ordered lists of numbers or terms. A sequence is an ordered list of numbers or terms where each term follows a pattern or rule. A series is the sum of the terms in a sequence. This article will explore sequences, series, and their applications in mathematics.
Algebraic+Expressions+and+Identities
Algebraic expressions involve variables and numbers combined using operations like addition and multiplication. Identities are equations that are always true, no matter the values of the variables, such as a2 - 2ab + b2 = (a - b)2. This document discusses algebraic expressions and identities, which are important concepts in algebra.
