Want values of trigonometric functions as degrees, and convert them too

[mouri11]

I haven't found any solution to this. sin 30 gives -0.98... instead of 0.5. Need to be able to change among these values.

Maybe, keep a toggle button for toggling between radians and degree.

Yes, I am keeping toggle buttons but I am not sure how to use it after sin x is calculated.

Like, in Casio fx-82ms,if you calculate sin x, you can specify whether x is in degrees or radians. Any way to specify that?

In casio fx-82ms, sin 30 is calculated, then if we change mode from radian to degrees(say), now we need to press on "equals to" again to calculate the new value. You can do something like that.
