These commands are used to specify angular units in a program. For practice, use
them in the following calculation examples:

Of these functions, the INT, ABS, SGN, and MDF can be entered by using l e tter
keys. Some other functions may also be entered with letter keys. For example, "sin
30" may be entered either by operating ~ 30 or
W UJ[Fl
30. For trigonomet-
ric and inverse trigonometric functions and coordinates conversion, the desired
angular unit must be specified in advance. In manual calculations, angular units may
be specified either by operating I
