Parametric Equations

</dt>
A set of equations in which the independent variables or coordinates are each expressed in terms of a parameter. </dd>
For example, instead of investigating y = f(x) or F(x,y) = 0 it is often advantageous to express both x and y in terms of a parameter u: x = g(u); y = G(u). The parameter may or may not have a useful geometric or physical interpretation. [[/a>|/a> ]]
