Trigonometry functions are very straightforward with the SciPlus-3300. Note that the values used in
trigonometry functions, and the result, are expressed in Degrees, Radians, or Gradians, as indicated by ‘D’
‘R’ or ‘G’ in the status line. The examples shown below assume the SciPlus-3300 is in “DEGREES” mode.

This simply toggles through Degrees, Radians, Gradians. The current
setting is indicated in the status line. After setting this parameter,
subsequent input values and the results of expressions are expressed
accordingly.
