Hello Everyone - When use a series of data and create a chart - then from that create a treadline to forecast future values - sometimes the formula Excel provides (used to forecast the future values) is, im guessing, to big or too long and Excel will place an E next to a number. Here is an example: y = 762870x + 5E+06 How can I see the equation in its entirety so I can use it? Thanks!

I assume that you mean "trendline", not "treadline"? 5E+06 means 5 * 10^6 You may want to try a function such as LINEST or LOGEST, depending on what sort of trendline you are looking at. -- David Biddulph MC wrote: > Hello Everyone - > > When use a series of data and create a chart - then from that create a > treadline to forecast future values - sometimes the formula Excel > provides (used to forecast the future values) is, im guessing, to big > or too long and Excel will place an E next to a number. > > Here is an example: y = 762870x + 5E+06 > > > How can I see the equation in its entirety so I can use it? > > > Thanks!

MC - Several possibilites: (1) Select the equation, and then Format it. Method depends on Excel version, which you didn't specify. (2) For a linear trendline, use the INTERCEPT and SLOPE worksheet functions (or array-entered LINEST, especially if you want diagnostics). (3) Or, for linear forecasts, use the array-entered TREND worksheet function. - Mike http://www.MikeMiddleton.com "MC" <MC@discussions.microsoft.com> wrote in message news:F2156CB2-3564-46C3-A90E-9B3DA64B01D1@microsoft.com...

Haha yes I did mean trendline thanks for that correction. I do not know what I was thinking when I wrote that. I do not know how to use the LINEST, TREND, or LOGEST functions, but I was using the trendline to forecast future expenses, assuming they increase in a linear fashion (which is more than likely not the case, but it works well enough). Thanks for the help - It is much appreciated David and Mike!

If you don't know how to use any Excel function (with the exception of DATEDIF), look it up in Excel help. -- David Biddulph MC wrote: > Haha yes I did mean trendline thanks for that correction.

I just installed Office mac 2004 student teacher edition on my brand new MacBook. I can't seem to use equation editor. Since I am a math teacher, that sucks - to say the least!

Hi, I created a bar chart in Excel from the following data: X Y 73 6.6 78 5.7 86 4.8 The SLOPE and the INTERCEPT functions returned -0.136 and 16.4448 respectively. The resulting equation is Y = -0.136X + 16.448 which seems good enough to me. Then I added a linear trendline to the chart. Excel displayed the following equation: Y = -0.9X + 7.5, R ^2 =1 which is way off (and it's not a rounding problem)!!! The data seemed farly linear to me, how come Excel can't come up with the right equation??? Thanks Jan M. Use an "XY (Scatter)" chart. When you...

Hi all, I've been searching the queries here and can't find an answer to what I'm hoping is a simple query . . . I want my equation to ensure that any minus values are returned as 0 but positive values should remain true. THis needs to be within the original equation as opposed to a separate equation doing a find and replace. Appreciate any answers (preferably by e-mail!). Jim. Try using IF(), for example: Put in C1: =IF((A1-B1)<0,0,A1-B1) which will return 0 if (A1-B1) results in a minus value with zero & positive values remaining true Hope the above helps. M...

I'm trying to use Word 2007's built-in equation functionality, but often times when I try to type a letter in an equation (e.g. y=2x), the letters (so the y and the x) just show up as boxes. The only way it seems I can get it working is to copy and paste from a previous equation that worked with letters, clear out the irrelevant equation and type in the new one. However, I feel there MUST be a better way of doing this. Any help would be appreciated. The 'old' equation editor is included with Office 2007 and works just as before. It is not installed by default so...
