Coordinate Conversion
θ
Converts rectangular coordinates to polar coordinates (x, y r,
)
Converts polar coordinates to rectangular coordinates (r,
x, y)
θ
Splits data used for dual-variable data input.
Determine the polar coordinates (r, ) when the
rectangular coordinates of Point P are (x = 7, y = 3).
θ
APPLICATIONS:
Coordinate conversion is often used in mathematics and engineering, espe-
cially for impedance calculations in electronics and electrical engineering.
