R▶Pr(

:R▶Pr(x,y)

This receives a set of rectangular coordinates, than returns the equivalent radius in polar mode.

    :R▶Pr(xlist,ylist)
(n) :P▶Rr(xmatrix,ymatrix)

If both containers are the same size, returns a new container containing the results of the R▶Pr command at each index in the containers

Location

• 2ND + APPS (ANLGE)
• ANGLE
• 5:R▶Pr(

Example

:ClrHome
:Disp "INPUT RECT COORD"
:Prompt X,Y
:Disp "POLAR COORD IS:"
:Output(5,1,"R=",R▶Pr(X,Y)
:Output(6,1,"θ=",R▶Pθ(X,Y)

This prompts for a rectangular coordinate. Then, it displays the equivalent polar coordinate.
