Trouble opening Word 2007 for Windows files with equations on my Word 2008 for Mac
Operating System: Mac OS X 10.5 (Leopard)
I use Word 2008 for Mac but when I try to open a Word 2007 for Windows file from a student with equations, all the equations are nonsensical. Any hints?
FWIW, not being familiar with this area of Mac Word, when I try to open
a Word 2007 document containing a Word 2007 equation (not the older type
of equations) I see a dialog box that says that Word 2007 equations are
not supported in Word 2008, that the equations will be preserved so that
they will be visible if re-opened in Word 2007, but will "displ...equation of a curve
I created a simple curve on excel using data points.How can I get the
polynomial equation of the curve ?
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.
Or you can use LINEST; see

I have two lines one linear (y=mx+c) and one exponential (y=c^bx) and
they intercept each other. I believe it is possible to calculate where
the lines intercept. Although I can do this by graphing the data, it
takes time and allows for user error so a calculation would speed
things along greatly.
So for the first line using the equation y=mx+c the numbers for the
13kPa line are y=0.0021x+9e-16
And for the exponential line (y=c^bx) which we produce to using the
myograph is y=0.0022^0.0046x (^=Exp)
I know that the two lines intercept at 1613. But no matter what I try

In Excel how do you set up a 3 variable linear programming
problem on a spreadsheet with a a number of constaints
See the tutorials and examples at www.solver.com.
Or, search your drive for the file solvsamp.xls, which is installed when
Solver is installed and which has a 3-variable nonlinear example that is
easily converted to linear.

I want to graph the linear equation y = 2x + 4 in microsoft excel. How do I
do this? On my TI-83 Plus I could easily do this. I also know I could create
a data table and use the table of values to chart the line in excel. But I
want just enter the equation in excel and have excel graph it. Thanks.

i need to find a equation of ellipse which join two points, how do i
get the equation from the excell sheet?
You have two points: (x1,y1) and (x2,y2)
The equation of an ellipse is (x - h)2 / a2 + (y - k)2 / b2 = 1
This has four unknowns and you have only 2 data points
i) (x1 - h)2 / a2 + (y1 - k)2 / b2 = 1
ii) (x2 - h)2 / a2 + (y2 - k)2 / b2 = 1
If we assume the ellipse has it centre at the origin then you have
i) x12 / a2 + y12 / b2 = 1
ii) x22 / a2 + y22 / b2 = 1
Two equations & two unknowns; some simple algebra get you a and b

The math behide this solution is quite simple:
if a polynomial equation f(x)=0 has roots, let's say x1,x2,��xn,then
f(x) can be converted to another format as
(x-x1)*(x-x2)*(x-x3)*�...*(x-xn) = 0
So what we do here is use goal-seek to find it's first root(x1)
then use f(x) / (x-x1) as a new equation, easy to say the new one is
(x-x2)*(x-x3)*�...*(x-xn) = 0
repeat the procedure above,we can get all the roots one by one.

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?
I assume that you mean "trendline", not "treadline"?
5E+06 means 5 * 10^6

I am kind of new to excel and was wondering if excel is capable of
doing linear increments. I want increments that can vary, meaning in
one case i want to go from 0 to 10 in increments of 2 and in other
cases i want to go from 0 to 10 in increments of 5. The number of cells
change. Is it possible for excel to do this w/o having to specify the
number of cells needed?
