The degree symbol must be entered following the degree number. A popup window with symbols can be brought up by clicking the button in the far left of the input box, where the degree symbol can be found at the bottom of the window (in Geogebra 5).
I think my point of confusion stemmed from the angle unit setting. When setting the angle unit in a calculator, any functions which expect angle values will use that angle unit setting, where in Geogebra, only graphing is affected by the angle unit setting. Also in Geogebra, there is nothing in the preferences window stating that the angle unit setting only affects graphing.
