Solving System Of 3 Nonlinear Equations
Feb 12, 2013I have a system of 3 equations with 3 unknowns that I would like to solve in Excel.
The equations are
24.792 = A*e^(B/(100-C))
9.857 = A*e^(B/(70-C))
4.590 = A*e^(B/(40-C))
Where e is the exponential function.
Polynomial Equations
May 14, 2006y = 1.083333333x4 - 7.3333333x3 + 16.416667x2 - 6.16667x + 4
Above is the polynomial equation of a trend line as shown on my chart, I have extracted the numbers into separate cells using LINEST, so now I have in cells A20 to E20 the numbers 1.083333333, -7.333333, 16.416667, -6.16667 and 4 respectively.With a "y" value of 25 how do I go about solving for a value of "x".
I've been stubbornly struggling with this on and off for a couple of weeks now and I'm not getting any closer to working it out and the websites I've found explaining the procedure all seem to go over my head by the time I get into the fourth or fifth paragraph.
Solving Equations Using VBA
Oct 24, 2013I am given the function
y = a x + b
And I am supposed to ask the user to enter a value for a and b twice
So I could have 2 equations and solve them
The problem is I am not sure how to solve the 2 equations using VBA?

Solving Polynomial Equations
Feb 16, 2007I don't actually own Excel as yet - but I'm wondering if someone could tell me whether Excel is capable of solving what I'm told are 'polynomial equations'. An example of the sort of equation I hope to solve is: d/(1.18 + d) + d/(1.86 + d) + d/(9 + d) + d/(8.8 + d) = 2
d=? {I happen to know d = 3.65(approx) in this example btw}
Often there will be many more than four terms...
Solve Set Of Simultaneous Equations
Oct 9, 2007I am trying to solve a set of simultaneous equations by using SolverOk function in VBA.
I dont want to use the 'SetCell' option so, I wrote the following

SolverAdd CellRef:=Range("AK4:AK6"), Relation:=2, FormulaText:="0"
SolverSolve
but I get an internal memory error. However, if I use the solver dialog box directly from excel and not through a macro and keep the 'Set Target Cell' as empty, I get the right solution.
Optimizing Equations Using Scope Definitions?
Mar 30, 2014I'm trying to find definitions/commands to make excel find the best combinations of several defined scopes and restrictions to make an output number as high as possible.
This is by using a combination of several different equations, maybe excel has a magic trick for all the variables and formulas.

Apr 4, 2014I am trying to analytically solve an equation to establish a physical value. Unfortunately, it's difficult to do the algebra, so it needs to be done this way.

Entering Finance Equations Into Excel Manually?
Dec 26, 2013I am about to take a corporate finance course. The textbook uses a ton of basic (complex to me) equations to calculate interest rates, bond premiums, dividend reinvestment scenarios, etc.
I know that Excel has a bunch of specific functions to calculate interest, NPV, etc. but I am NOT interested in using those because I would like to have Excel "do the math" once I enter the formulas (or parts of formulas) correctly.
how to enter the equations below into Excel without using built-in formulas (I'm also not looking to use the Equation editor because I actually to calculate the answers, not just have the visual look/feel of the equation).
1R2 = [(1 + .0194)(1 + .03)]1/2 - 1
If done correctly, 1R2 in the above should equal 2.47%. I am totally fine doing parts of this in separate cells if necessary.
And something more complicated like the below. I wrote out the word "delta" because I don't know how to create the "triangle" symbol for delta on this forum post. According to the text, for securities with semiannual receipt (compounding) of interest, it is represented as:
-D = (delta P / P) / ((delta r sub b) / (1 + (r sub b)/2)))
Or in English, I believe that can be expressed as "negative D equals the quotient of delta P divided by P (in the numerator) divided by the following: delta r sub b divided by the quantity 1 plus r sub b divided by 2"
And finally
V sub b = 1000 / [1 + (.10/2)]2(4) + 50 times the following compound bracketed expression [1 - (1 / [1 + (.10/2)]2(4)] divided by (.10/2)]

Excel 2010 :: Algebra Equations - Calculate By Grouping Like Numbers
Dec 31, 2013I had a question about adding numbers, sort of like algebra equations (best description I can think of) into a spread sheet. Example:

Using IF With Larger Equations, If Value = 9 Then Display "0"?
Jan 13, 2009I am using the following equation to add together up to eight different sound levels:
=10*LOG(10^H14+10^I14+10^J14+10^K14+10^L14+10^M14+10^N14+10^O14)
It works perfectly, except that due to the nature of the equation, if there are no values entered for any sound levels the answer will be 9. Is there any way to check to see if any values are present? I've been looking into IF functions and I've tried (unsuccessfully):
=IF([=10*LOG(10^H14+10^I14+10^J14+10^K14+10^L14+10^M14+10^N14+10^O14)]=9, 0, [10*LOG(10^H14+10^I14+10^J14+10^K14+10^L14+10^M14+10^N14+10^O14)])

Jun 27, 2007Currently I'm working on a prediction game using excel. Can excel do the tabulation itself(Points awarded) if I just key in the result? Can anyone help me? Thanks in advance.
Examples below,
Result 3-1
Name Predicted Scored Points
Alex 3-1 5
Brian 4-1 4
Charlie 2-0 3
Derrick 3-3 1
Eric 0-2 0
Point System:
1 point for correct goals/no goal by either both teams
3 points for correct result ( Win, Lose, or Draw - say result is 3-1, 3 points if you predicted a Chelsea 2-0 win)
5 points for correct match results
No points for incorrect score and results.

Setup New Inventory System?
Aug 26, 2013We have 100+ clients. Each client has inventory in our warehouse. Every day we write down how many items went out to our client on a piece of paper and subtract that number to get a balance inventory. When we run low, we order more on a new FO number. What is the best approach for tracking this? I was thinking one way is to put our clients in a drop box at the top of the page and then the data will appear at the bottom, however I can't get that to work. I am trying filters to see, but I am unable to subtract the balance automatically from the last FO# and from the correct area.
Is there a way to choose a client and product at the top of the page and have the tracking below?
