This may sound a little unfair. After all, a standard Microsoft installation would include something called Equation Editor. Suffice to say, it wasn‘t advertised in the promotional videos. Software like Matlab was considered vastly superior and had the added advantage that you could analyze the equations as well. Anyway, the good news is that Microsoft has taken a big step forwards with Office 2010 and it‘s now possible to correctly display formulas in a pretty painless fashion. In Excel 2010, you should select the Insert ribbon, and click Equation. This creates a textbox and brings up a whole new ribbon with options for inserting equations. As well as providing easy access to the main Greek symbols, Microsoft have provided quick access to a number of simple functions, such as fractions and exponentials.
If a user tries to open a Workbook that is already open, then they normally get a message saying that the File is locked by a certain user and would you like to open the file in Read only mode. However, you can open a workbook in shared mode by following these steps. First open the file that you want to share, then once the workbook is open, go to the Tools menu and choose Share Workbook from the drop down menu. The Share Workbook dialog box will now appear. To enable sharing, you simply click once on the Allow Sharing check box, so that it has a tick. Once you do this other people will now be able to use your Excel workbook whilst you are working on it.
