Conversions
The following functions provide useful conversions:
-
converts an angle measured in radians to degrees.
-
converts an angle measured in degrees to radians.
-
converts the polar coordinate (r, theta) into
the rectangular coordinate (x, y). Theta should be expressed in
units corresponding to the current angular mode.
-
converts the rectangular coordinate (x, y)
into the polar coordinate (r, theta). Theta is returned in units
corresponding to the current angular mode.
-
converts a number from a decimal-fraction
(H.h) to minutes-second (H.MMSSs) format. This is useful for time
expressed in hours and angles expressed in degrees.
-
converts a number in minutes-second format to
decimal-fraction format. All of the calculator's functions (except
this one) require numbers to be in decimal-fraction format.
For example,
- Press
to convert pi to
180 degrees.
- Press
to convert 360 degrees to 2 pi radians.
- Press
to
convert the rectangular coordinate (x = 1, y = 2) to the polar
coordinate (magnitude = 2.2361, angle = 63.4349 degrees). (Press
button to view theta.)
- Press
to convert 2.5 hours to 2
hours 30 minutes (2.30000 or 2"30'00.0).
- Press
to convert 4 hours 23 minutes
48 seconds to 4.3967 hours.
