# Delta Math: A Comparison to Khan Academy The Lower-case delta (D) is the discriminant of a polynomial equation, and in calculus, the letter represents a change in a variable’s value. It can also represent any angle in any geometric shape. In this article, we’ll discuss DeltaMath Plus’ cost and features. In addition, we’ll look at how DeltaMath’s adaptive technology works. And we’ll discuss how DeltaMath’s adaptive learning features can help your students improve their math skills.

## The lower-case delta (D) represents a change in the value of a variable in calculus

The Greek letter “delta,” or the Greek letter dalet, stands for “change,” and is the fourth letter in the Greek alphabet. In mathematics, the Delta symbol indicates a change in the value of a variable. It’s a common symbol in word problems, which means the value of variable changes over time. The Greek letter “Da” is also a useful symbol for many mathematical concepts.

In more advanced mathematics, lower-case delta (D) may have a more specific function. In trigonometry, for example, it represents the area of a triangle or the difference between two sets of elements. It is also used as the discriminant of a polynomial equation. But in most cases, the meaning of a delta symbol is irrelevant until you’re at the advanced levels of mathematics.

## The lower-case delta (D) represents the discriminant of a polynomial equation

The delta symbol is commonly used to represent the discriminant of a polynomials equation. However, the discriminant of a polynomial equation is not always the same as the area of a triangle. In some cases, the discriminant may refer to the difference between two variables, but this is rare. The delta symbol is used in algebra, geometry, and trigonometry to represent the difference between two variables.

The discriminant of a polynomial is a function of the coefficients of the equation and gives information about the type of solution it produces. There are two real roots of a quadratic equation, one complex root, or no solution at all. The delta symbol (D) is a Greek letter that can represent any angle in a geometric shape. The roots of geometry are thought to be derived from ancient Greek works. Mathematicians later denoted angles with Greek letters.

## Lower-case delta (D) may represent an angle in any geometric shape

The lower-case delta (D) may represent an edge, corner, or angle of any geometric shape. The mathematician’s use of the letter D in marking angles can be traced back to ancient Greece. The Greek letters d, g, and h are used to signify angles in geometry. Despite their common use today, it’s easy to get confused about what these letters mean.

The letter D is a symbol in the Greek alphabet, representing a voiced dental plosive /d/. In modern typography, this letter is romanized as a d, dh, or h. Its many uses are as varied as its pronunciation. In addition to a mathematical symbol, the lower-case delta is a common name for the delta of a river. While it’s not as common as the upper-case delta, the name is reminiscent of the lower-case version.

## Cost of Delta Math Plus

A year’s subscription to DeltaMath Plus costs \$75. It includes several useful features that make this math software worth its price. Teachers can view individual student performance data, create their own assessment problems, and even track whether a student is using the program by watching videos. Students can also create their own problems to test their abilities. While many teachers have expressed concerns about the cost, it is worth considering the benefits that this math software can offer.

Parents are likely to benefit from improved math ability of their children. Using DeltaMath is an excellent option as it enables parents to observe the progress of their child’s skills and reflect on their own math proficiency. The diverse features offered by DeltaMath make it easy to use, and students will find a wide range of options to suit their needs. With DeltaMath, parents can unlock the true intellect of their children.

## Comparison to Khan Academy

A comparison of Delta Math to Khan Academy can be a daunting task, but it doesn’t have to be. Both programs feature thousands of skills and user-friendly interfaces. Students can copy and paste assignments and practice as much as they want, without worrying about marking or answering “is this right” questions. Both programs also offer videos for help on all skills. Students can easily hide videos, and teachers can track how much time students spend on each skill.

Both apps provide personalized instructions to guide students through their math assignments. More than one million students worldwide have found success with Math. The platform features a fast-paced, adaptive interface that develops new math skills through immediate feedback and specific hints. Besides, teachers can monitor individual students’ progress, assign complex homework and track individual student progress. However, some students struggle with DeltaMath answers. This can lead to cheating, especially for students who have a difficult time providing the answers themselves. Click here for more information
