Sciatica is a medical condition characterized by pain going down the leg from the lower back. This pain may go down the back, outside, or front of the leg. Typically, symptoms are only on one side of the body. Certain causes, however, may result in pain on both sides.
We say Distance is directly proportional to time and thatâs why this represents a direct relation. A Directly Proportional Graph describes the relationship of a graph in words and mathematically. When the two measured physical quantities are plotted to form a straight line, we say they are âproportionalâ to each other.
Variable y is directly proportional to the variable x. In mathematics, two variables are proportional if a change in one is always accompanied by a change in the other, and if the changes are always related by use of a constant multiplier. The constant is called the coefficient of proportionality or proportionality constant. 1  If one variable is always the product of the other and a constant, the two are said to be directly proportional. x and y are directly proportional if the ratio yx is constant.
