```Hi Naty

Right click on one of your data points and select Add trendline.
The trendline dialog boxes offers a number of options for
type of trendline, showing equations in chart etc.

```Well, thanks for the advice, but I think since my curve is not linear or
something, it doesn't give me the Add trendline option. My curve looks like a
3rd order polynomial.

```Hi Naty,

You have to be using an XY Scatter chart, not a line graph.
The scatter graph allows for polynomials from 2nd to 6th orders
amongst other options. How is your curve and data setup?

equation editor
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! Error message says somethng like - make sure it has been installed, or maybe it has been renamed etc. All I did was install. Short of using my 2nd product key to fix the problem what can I check. Find brings up no info on equation editor. I don't think Eq Ed is automatically installed with a standard installation of Office 2004 - it needs to be included in a custom install or added later. You can install it no...

MS Word equation editor won't open when double-clicking on an equation
Version: 2008 Operating System: Mac OS X 10.6 (Snow Leopard) Processor: Intel I created a document (.docx) using the Office 2008 version of MS Word some time ago (2 months or so). Recently I wanted to correct an equation in that document and re-opened the document (on the same system and with the &quot;same&quot; copy of Word) and attempted to double-click the equation to edit it. Instead of the equation editor I get the &quot;Format Picture&quot; dialog box. In the interim I did install an update (I tend to try to stay up to date) and am at 12.2.4 (100205). <br><...

Linear trendline:wrong equation
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...

Trendline equation not giving correct results
I was trying to form a trendline with following data : Y X 1.128 -20 1.128 -15 1.128 -10 1.128 -6 1.111 -5 1.084 0 1.056 5 1.0276 10 1 15 0.971 20 0.944 25 0.9144 30 0.884 35 0.8524 40 0.82 45 0.788 50 After plotting the chart, I added trendline (Polynominal with order 6) alongwith its equation which read as below : y = 6E-07x6 - 3E-05x5 + 0.0006x4 - 0.0057x3 + 0.0215x2 - 0.0318x + 1.1429 and R2 = 0.9998 The trendline in the chart neatly fitted over the curve. However, when I used above equation and fed in same values of X as shown above the computed results are entirley different fro...

Set minimum values for equation results
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...

Equation Editor- problem when editing an equation
I use Equation Editor a great deal, and I constantly have the same problem. If I create an equation, and later go back to edit it, the font and spacing of the equation change. I try to resize the equation by enlarging or decreasing the size of the window, but all that I accomplish is either "bunching up" or "stretching" my equation. How do I get it back to what it looked like originally? ...

I am wondering if someone could help me solve this equation
A car wash makes \$4000 profit on sunny days and loses \$4000 on non-sunny days. Assuming independence, if it is sunny 75% of the days, (and, therefore NOT sunny 25% of the days) what is the expected (daily) profit (or loss) for the car wash? (MEAN = EXPECTED VALUE) Let me know via email or can you please forward me to someone who can help me with this formula? Thank you.

Letters in Equations
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...

Equation: Fractions
Word 2007 Insert | Equation When I type a number divided by a fraction using the Stacked fraction and Small fraction templates on the Equation Ribbon, the Stacked fraction bar automatically resizes to fit making it difficult to easily differentiate between the two fraction bars.

I want the Stacked fraction bar to be noticeably longer than the Small fraction bar. I know I can use Linear or Skewed instead of the Small fraction but I don't want to. There i...

transparent curves?
I've drawn a couple asymptotic lines (dotted lines) on a chart and would like to know if there is a way to draw the actual curve (which follows these lines) to make it look like it was drawn with a highlighter. In other words, I'd like the actual curve to be transparent or semi-transparent so that you can still see the dotted lines. Thanks for any help, including telling me it can't be done.
