A trace command allows to draw the locus of a point depending on a numerical variable. It has the following syntax:
trace(x, x', x'' [, f])
This statement has to be followed by at least one point valued expression
enclosed in braces (depending on variable x). Parameters x' and x" are the
lower and upper bounds of x. The expression has to be defined for each value of
the interval. If not, it may lead to spurious results or sometimes (with
eukleides) to an error message. Within the braces, in order to
perform intermediate computations, it is possible to add any sequence of
statements before the expression. If f is given, it overrides the current
drawing style. Permitted values of f are full, dashed
and dotted.
