In mathematics, when the dependent variable is not proportional to the independent variable. The function does not vary directly with the input. Example: y=sin (x).
In mathematics, when the dependent variable is not proportional to the independent variable. The function does not vary directly with the input. Example: y=sin (x).
X = YY = X=======these are directly proportionalX = 1/YY = 1/X========these are inversely proportionalTry a few inserted numbers and graph these to see, visually, the difference.
A variable, Y, is inversely proportional to another variable, X if XY = k for some positive constant k. An equivalent formulation is Y = k/X. What this means is that if you double X, then Y is halved. If you treble X then Y is reduced to a third etc.
The greek letter "alpha" (α) for both. If x is directly proportional to y, you could say x α y. For inversely proportional, you would say something like x α 1/y, or x α y^-1, as in, directly proportional to the inverse.
When two variables are directly proportional, it means that as one variable increases, the other variable also increases at a constant rate. In mathematical terms, this relationship can be expressed as y = kx, where y is one variable, x is the other variable, and k is a constant value.
In physics, direct square proportionality refers to relationships where one variable is directly proportional to the square of another variable. For example, in Newton's law of universal gravitation, the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
If a variable (such as y) is directly proportional to another variable (such as x), they both increase and decrease simultaneously. An equation for two directly proportional variables is:y = axIt's sort of like a linear equation, but it always goes through the origin.An example is y = 6x. Notice that it forms a straight line and crosses the origin, and that y and x increase in the same direction.
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.

One variable is directly proportional to another if increasing/decreasing the first variable increases/decreases the second variable by the same proportion. For example, consider the equation a = b x c. "a" is directly proportional to both "b" and "c". If you double "b" or "c" then "a" is also doubled etc...
