Whenever there is a negative under the radical sign, it comes out from underneath as i since the problem will contain a square root of -1. When simplifying these radical numbers in terms of i, follow the usual rules for simplifying radicals and treat the i with the rules for working with a variable. Examples:
The location of the Personal Macro Workbook is a little confusing, because older versions of Excel stored it in an XLSTART folder buried inside the Program Files folder. Even though you canât write any files to it, Excel 2007 and Excel 2010 also have XLSTART folders inside the Program Files directory.
I'm using Excel 2002, and the personal macro workbook has apparently vanished (or whatever seems more plausible). I honestly don't know what happened, but I went to record a macro just now, and got the following: Personal Macro Workbook in the startup folder must stay open for recording..
