Inputting and Editing Cell Data

uFormula Input Example

In this example, we will input the 60 into cell A1, and then input the following formulas into the indicated cells: B1: =sin(A1), B2: =cos(A1), B3: =tan(A1), B4: =B1/B2

We will also show that the values produced by B3 and B4 are the same even if we change the value of A1, so sin (x) cos (x) = tan (x) holds true.

Note

This example assumes that the calculator is configured as follows.

The “Move” setting on the Setup screen (page 1-8-5) is “Low” (initial default). The “Angle” setting on the Setup screen is “Deg”.

This example also uses cell referencing. For more information about cell referencing, see page 9-4-5.

uTo input formulas

1.Move the cell cursor to cell A1, and then input gaw.

2.Move the cell cursor to cell B1, and then input the following.

!.(=)sav(A)bw

Pressing w will cause the cell cursor to move to cell B2.

3.Perform the following procedures to input the formulas for cells B2 through B4.

!.(=)cav(A)bw !.(=)tav(A)bw !.(=)al(B)b/al(B)cw

4.Move the cell cursor to cell A1, and then input daw.

This will cause the updated values to appear in cells B1 through B4, based on re-

calculation using the new value you input in cell A1. Since the values produced by

B3 and B4 are the same even if we change the value of A1, sin (x) cos (x) = tan (x) holds true.
