What can Delta Math see?
Teachers are able to see the IP addresses of their students for any given problem solved in order to ensure that multiple accounts are not signing in from the same computer possibly indicating one student is signing into another student’s account to complete work under a false identity.

What does delta mean in math?
Delta Symbol: Change Uppercase delta (Δ) at most times means “change” or “the change” in maths. Consider an example, in which a variable x stands for the movement of an object. So, “Δx” means “the change in movement.” Scientists make use of this mathematical meaning of delta in various branches of science.
What does Upside Down Delta mean in math?
The upside-down capital delta symbol. , also called “nabla” used to denote the gradient and other vector derivatives.
What does an upside down V mean?
raised to power
What do you call an upside down triangle?
The nabla is a triangular symbol resembling an inverted Greek delta: or ∇.
What is the difference between U and upside down U?
It means the Intersection of a set. For example, IF you have a set of even numbers and a set of odd numbers, the Union ‘U’ of these two sets would be ALL numbers. But, the Intersection (upside down U) would mean that NONE of the numbers in Evens are in common with any of the Odds in the second set.
What does the U symbol in math mean?
∪ The symbol ∪ means union. Given two sets S and T, S ∪ T is used to denote the set {x|x ∈ S or x ∈ T}. For example {1,2,3}∪{3,4,5} = {1,2,3,4,5}. ∩ The symbol ∩ means intersection.
What does a ∩ B mean?
In mathematics, the intersection of two sets A and B, denoted by A ∩ B, is the set containing all elements of A that also belong to B (or equivalently, all elements of B that also belong to A).
What does B mean in a number?
It’s a way to denote to PHP that this number is a binary number. Otherwise, it’s going to think it’s a normal decimal number. The numbers rely on different prefixes to denote that they should be calculated as something other than base 10 numbers.
What does M and B stand for in math?
change in x-value. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
What does B mean in slope intercept form?
m is the slope of the line (change in y/change in x) and b is the y intercept of the line (where the line crosses the y axis).
What does a slope intercept equation look like?
The slope-intercept form is a way to describe the equation of a straight line (a linear function). It appears in the form of y=mx+b, where m and b are constants and y and x are variables.
How do you find the vertical intercept given two points?
This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
What is the vertical intercept of an equation?
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
Is vertical intercept the same as vertex?
In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. The y -intercept is the point at which the parabola crosses the y -axis. The x -intercepts are the points at which the parabola crosses the x -axis.
What is a vertex that is the highest point?
One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.
How do you tell if a function has a minimum or maximum value?
1 Expert Answer The second degree polynomial f(x) is of the form ax2+bx+c. A rule of thumb, if a is positive, the function has a minimum. If a is negative, the function has a maximum. The maximum/minimum are given by x=-b/(2a).
What is the maximum and minimum of a parabola called?
The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of a parabola.
