The distance between two points is calculated using the distance formula d = √ (x2 - x1)2 + (y2 - y1)2, where (x1,y1) and (x2,y2) are the coordinates of the two points and "d" indicates the distance. The distance formul... More »

Use the distance formula and a calculator to find the distance between two points. The distance formula works because if two points are plotted on a graph, their direct line is the hypotenuse of a right triangle; thus, t... More »

In math, the term "distance between two points" refers to the length of a straight line drawn between the two points on an x-y axis. The distance can be determined by finding the change in the y axis and the the x axis a... More »

Examples of mathematical functions include y = x + 2, f(x) = 2x, and y = 3x - 5. Any mathematical statement that relates an input to one output is a mathematical function. Many simple mathematical functions are written a... More »

The formula for calculating the slope of a line when given two points, (x1, y1) and (x2, y2), is the difference in y coordinates divided by the difference in x coordinates. The slope, denoted as the letter m, equals (y2 ... More »

To find a line's equation, identify two of the points through which the line passes, and then use the "x" and "y" coordinates to find the slope of the line, or the rate at which it climbs or falls. Use the slope to find ... More »

Graphing y=cot(x) is a process and involves first examining a table of the coordinates of the points that can satisfy the equation of y=cotx. First, students should create a column on a piece of paper or in Excel and lab... More »
