displays a menu to convert rectangular
coordinates (x, y) to polar coordinates (r,
æ
) or vice
versa. For each coordinate to which you are converting,
enter both values expressed in the format
from
which
you are converting, separated by a comma, then close
the parentheses with
O
before you complete the
operation with
V
. Set angle mode, as necessary,
before starting calculations.

Examples
Convert polar coordinates (r,
æ
)=(5, 30) into rectangular
coordinates. Then convert rectangular coordinates
(x, y)=(3, 4) into polar coordinates. Round all results to
1 decimal place.

(r,

)=(5, 30) converts to (x, y)=(4.3, 2.5). (x, y) = (3, 4)
converts to (r,
q
)=(5.0, 53.1).
