What does this symbol mean?

Eden,

This image is a vector representation of the mathematical symbol that is used to denote Proportionality.

The symbol is used to indicate whether the two values are proportional to each other.

The symbol means directly proportional.

It is different from that of constant of proportionality.

Hope this helps,

Nick

this symbol stands for "directly proportional" .

Assume that S is the amount of sugar that you put in your tea, and W is the sweetness of the tea. It is easy to imagine that the more sugar you pour, the more your tea will be sweet. Therefore we can say that the sweetness of the tea is directly proportional to the amount of sugar that you pour into it. The same Concept may be expressed writing:

W ∝ S

that you'll read it W is directly proportional to S.

cheers :-)

This is the symbol of proportionality.

It means proportional to.
