![]() That we can show an interval, or interval notation. To do in this video is get familiar with the notion of an interval, and also think about ways If the boundary expressions do both things, we use both notations. We have a square bracket after -1 because -1 IS included in the interval. We have a parenthesis in front of -4 because -4 is NOT included in the interval. In this case we mix the parenthesis and the square bracket. In the third example (the one you are citing), the one boundary expression includes "equal to" and one does not ( x is greater than -4 and x is less than or equal to -1). When the boundary does NOT includes the number (greater than or less than, but not equal to), we use parentheses to notate the interval. When Sal shows the notation for the second interval (pink writing), the boundary expressions do NOT include "equal to" ( x is greater than -1 and x is less than 4). When the boundary includes the number (equal to), we use the square brackets to notate the interval. ![]() If you go back and watch Sal show the notation of the first interval (blue writing), both boundary expressions include "equal to" ( x is greater than or equal to -3 and x is less than or equal to 2). Keep in mind that this is a type of mathematical notation and not Grammar of any language that uses this type of punctuation. In Interval Notation, you actually can have a parenthesis on one side and a bracket on the other and have the notation be correct. The range of motion of your fingers is the amount you can move them independently of each other.This is actually a pretty good question and it's good to see that you are paying attention. For example, the range of motion of your shoulder joint is the amount you can move the arm from side to side or up and down. Range of motion is the total movement a body part can make. Range is usually used to represent data that consists of continuous values, such as numbers, graphs, or charts. The maximum value of a range is the upper limit. The minimum value of a range is the lower limit. ![]() Range is the distance between the lower and upper limits of a set of data. The concept of range is essential in many physical processes and can be particularly important in predictive modeling. Range is also sometimes used to describe the difference between a maximum and minimum value in a time-series data set. Range is used in physics to describe the maximum difference between a high and low value in a given variable. ![]() The distance between the highest possible value of this number and the lowest possible value is 9, What does range mean in physics? Another example of a range is the difference between the number 0 and the number 9,976. The distance between these numbers is 2, and the range is 2. A common example of a range is the difference between the number 72 and the number 74. The range of a number is the distance between the lowest possible value and the highest possible value. If you have a list of numbers that range from -1 to 1, the range is 2. If you have a list of numbers that range from 5 to 20, the range is 15. It’s the distance between the highest and lowest numbers on a list, regardless of whether it’s a number line or a list of ordered items. Range is the distance between two numbers. ![]()
