kInputting a Constant (Value, Calculation Result, Number Sequence) into a Cell

A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1⋅2, etc.) that does not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit).

uTo input a number sequence automatically based on a function expression

1. Move the cell cursor to the cell where you want number sequence input to start.

•Under initial default settings, automatic input of the number sequence will proceed downwards from the start cell. You can specify a different direction using the “Move” setting as described on page 1-35.

2. Press 2(EDIT)5(SEQ) to display the Sequence screen, and then specify the function expression and values required to generate the required number sequence.

		You can input data for the item that is highlighted on
		the screen.
		Reference name of the cell selected in step 1
Item		Description
Expr	Input the function expression f(x) for generating the number sequence.
	Example: a+(X)x+bw (X2 + 1)
Var	Input the variable name used in the function expression input for Expr.
	Example: a+(X)w (X)
Start	Input the starting value (X1) of the value to be substituted for the variable
	specified by Var.
	Example: cw
End	Input the ending value (Xn) of the value to be substituted for the variable
	specified by Var.
	Example: baw
Incre	Input the increment value (m) for successive value of X1, as in: (X2 = X1 + m),
	(X3 = X2 + m), and so on. The number sequence is generated in the range of
	X1 + (n – 1) m < Xn.
	Example: cw
