d R³´P
d ! displays the R³´P menu, which has functions for converting coordinates between rectangular (x,y) and polar (r,q) format. Set Angle mode, as necessary, before starting calculations.
|
1:P ´Rx( |
Converts polar to rectangular and displays x. Syntax: P ´Rx(r,q) |
|
2:P ´Ry( |
Converts polar to rectangular and displays y. Syntax: P ´Ry(r,q) |
|
3:R ´Pr( |
Converts rectangular to polar and displays r. Syntax: R ´Pr(x,y) |
|
4:R ´Pq( |
Converts rectangular to polar and displays q. Syntax: R ´Pq(x,y) |
Example
Convert polar coordinates (r,q) = (5,30) into rectangular coordinates. Then convert rectangular coordinates (x,y) = (3,4) into polar coordinates. Round decimal results to one decimal place.

Converting (r,q) = (5,30) gives (x,y) = (
,
) and (x,y) = (3,4) gives
(r,q) = (5.0,53.1).
