From the van der Waals equation given atthe start of the exercise our initial formula might be = (R_ * B8) / (A9 - b) - (a / (A9 * A9) ). This has some redundant parentheses, but these were added to help read the formula. The named cells and the named constant will always be absolute references. We need the reference to B8 (the T term) to always pointto row 8 and the reference toA9 (the Vterm) always to point to column A This analysis of the problem helps us modify the formula to that shown below.

J I. Format the cells to display five places. (c) The final step to find the solutions is to compute A-le. -J ]. 10 The solutions have now been found. We may wish to check that these agree with the system of equations. (d) Name the cells 010:012 asx,'y- and z, respectively. (e) The formulas in row 15 reading from leftto right are: =A51

If Al0 holds a nonnumber, then =SQRT(Al) cannot give a valid result, so it returns an error val ue (in this case #VALUEl). The error values are: #DIVjO! #NAME? #NjA #NULL! Division by zero. This would be the result, for example, of=AljBl ifBl hadazero value. Note that a blank cell is treated as having a zero value when used in a numeric context like this. This results when a formula contains an undefined variable or function name. No value is available. A result has no value. 46 A Guide to Microsoft Excel 2007 for Scientists and Engineers # NUM!
