5 days ago · The definition of a function of two variables is very similar to the definition for a function of one variable. The main difference is that, instead of mapping values of one variable to values of another variable, we map ordered pairs of variables to another variable.
1 day ago · e. In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
2 days ago · In mathematics, a matrix ( pl.: matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or property of such an object. For example, is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a " matrix ...

2 days ago · Discrete mathematics is the study of mathematical structures that are countable or otherwise distinct and separable. Examples of structures that are discrete are combinations, graphs, and logical statements. Discrete structures can be finite or infinite. Discrete mathematics is in contrast to continuous mathematics, which deals with structures which can range in value over the real numbers, or ...
5 days ago · Algebra, branch of mathematics in which arithmetical operations and formal manipulations are applied to abstract symbols rather than specific numbers. This article presents algebra’s history, tracing the evolution of the equation, number systems, symbols, and the modern abstract structural view of algebra.
2 days ago · Try This. In this explainer, we will learn how to graph cubic functions, write their rules from their graphs, and identify their features. We will focus on the standard cubic function, 𝑓 ( 𝑥) = 𝑥 . Creating a table of values with integer values of 𝑥 from − 2 ≤ 𝑥 ≤ 2, we can then graph the function. 𝑥.
