HP Prime Graphing NW280AAABA manual Special Locus places

Locus	Takes two points as its arguments: the first is the point whose
	possible locations form the locus; the second is a point on an
	object. This second point drives the first through its locus as the
	second moves on its object.
	In the example at the right,
	circle C has been drawn and
	point D is a point placed on
	C (using the Point On
	function described above).
	Point I is a translation of
	point D. Choosing Curve >
	Special > Locus places
	locus( on the entry line. Complete the command as
	locus(GI,GD) and point I traces a path (its locus) that
	parallels point D as it moves around the circle to which it is
	constrained.
Plot	You can plot expressions of the following types in Plot view:
	•	Function
	•	Parametric
	•	Polar
	•	Sequence
	Tap	, select Plot, and

then the type of expression you want to plot. The entry line is enabled for you to define the expression.

Note that the variables you specify for an expression must be in lowercase.

In this example, Function has been selected as the plot type and the graph of y = 1/ x is plotted.
