TRIGONOMETRY FUNCTIONS

All the trigonometric functions can take two forms of input-radians and degrees. If you just type in a number, the Calculator assumes the number is in radians. To enter a number

in degrees, press the degree sign				after inputting the number.
	Function	Operation			Display
	SINE		60		sin 60

	ARC TANGENT		60		atn 60
					= 1.55413
	ARC TANGENT		60		atn 60°
					= – – E – –
					(atn 60°
					produces an error)
