WebVariable. In algebra, a variable is usually a letter or other symbol that stands for a number or quantity that may vary. Variables can also be used to represent functions as well as quantities in other mathematical disciplines. The most commonly used variable in algebra is "x." Below is an example of a simple algebraic equation. x + 2 = 4. The dependent variable is a variable whose value is determined by the quantity another variable takes. For instance, in the equation y = 2x + 3, x can take any value, like 1, 2, 3. However, the value of y will depend on the value of x. So, if x = 1, y will become 5, and if x = 2, y will become 7, and so on. Therefore, y is … See more In real-life there are things that remain constant like your date of birth. However, there are things that vary with time and place like … See more An independent variable in an algebraic equation is one whose values are unaffected by changes. If an algebraic equation has two variables, x, and y, and each value of x is related to any other value of y, then x is … See more 動画送る無料
Variable (mathematics) - Wikipedia
WebIn other words, a variable is a symbol for a number where the value is not known. For example, x + 5 = 10. Here “x” is a variable. The value of the variable “x” can be easily found by solving the equation. In this case, if the equation is solved, the value of the variable “x” is obtained as 5. It means that x = 5. WebSee video transcript. So multivariable functions are all about associating points in one space with points in another space. For example, a function like f (x, y) = x^2 y f (x,y) = x2y, which has a two-variable input and a single-variable output, associates points in … WebExample: in x + 2 = 6, x is the variable. Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a … 動画送る方法 パソコン
