Paper Calculator Keypad

The Paper Calculator is printed on the inside back cover of Livescribe notebooks. Following is a list of the buttons on the Paper Calculator.

	Returns the percentage value of the number.
	Returns the factorial of number n.
	Returns the square of the number.
	Returns the square root of the number.
	Returns the inverse of the number.
	Raise a number y to the power of a number x.
	Returns Pi.
	Returns 10 to the x power.
	Returns e to the x power (the natural exponential. e is approximately 2.71828...
	Returns the base 10 logarithm of the number.
	Returns the natural logarithm of the number.
	Generates a random number between 0 and 1.

	Cosine of the number.
	Arc-Cosine of the number.
	Tangent of the number.
	Arc-Tangent of the number.
	Sine of the number.
	Arc-Sine of the number.
	Trigonometric calculations such as sine, cosine, and tangent must be made in degree, radian, or gradian mode. The calculator is in degree mode by default, and returns to degree each time you power off your smartpen. The DRG button toggles between Degree, Radian and Gradian mode. If you use a trigonometry function, or use the DRG key to change modes, the smartpen screen shows the indicator of the current mode. Note: You cannot use the DRG key to convert a completed calculation. Use it to set the mode before beginning the calculation.
