Analytically Solving Equations To Establish Physical Value
Apr 4, 2014
I 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.
I have an experimental value for this in "J2", so what I want to do is change F2 to that "I2" is equal to "J2"
Is it possible to get excel to match these values - I have about 200 different cells of this?
The formula is in cell "I2"
=B2*((1-(C2/D2)*((F2/G2)^1.2))^-1.5125)
I 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}
The above formula is not working as in A9, I have a formula although there is no physical text in the cell as the criteria applied is false. However, B9 still appears.
I am using the following code to find out if a file is open or not. The file name and directory is base on a cell value.
Sub SumTransfer111() 'Establish file path and file name based on cell value J5 (say 15204) fname = Range("J5") dirname = Int(fname / 100) * 100 dirname = dirname & " - " & dirname + 99 dirnamesub = Range("J5") Const sRoots As String = "S:MTL_DATAJobs" Dim sPaths As String Dim i As Integer sPaths = sRoots & dirname & "" & dirnamesub & "" & "Job_Cost_Summary_" & fname 'Establish if file is open Dim blnWorkbookIsOpen As Boolean.,.................
i'm trying to simulate badminton match with MS Excel..
i just want to make this project simple..
|..A..|..vs..|..B..| Player A vs Player B
Two players compete in a match.The possibility is 50% for both players to win.However,to make it real,each player have their own strength and ability.For this project,i just indicate 3 which is smash power,net power and stamina.[/size]
Ability:Smash Net Stamina
Players with more ability have more advantage.How can i relate it with the final score?
Scoring system:2 or 3 set in a match (3rd set is when both tied at 1-1) A match is the best of three games. Played with 21 points If the score reaches 20-all, then the game continues until one side gains a two point lead (such as 24-22), up to a maximum of 30 points (30-29 is a winning score)
In MS Excel:
...|Player A|...vs...|Player B|... <--Player A vs Player B
............|SIMULATE!|............ <--When I click Simulate!,scores appear
| 1st Set | 2nd Set | 3rd Set | <--Here where the scores appear
|............| Smash |............| <--Comparison of ability(can be edited) |............| Net |............| |............| Stamina |............|
Problem solving multiplication of two matrices with entries decimal in vba code:
Code: Option Explicit
Public MatrixA(30, 30) As Long Public MatrixB(30, 30) As Long Public MatrixC(30, 30) As Long Public RowA As Integer Public ColA As Integer Public RowB As Integer Public ColB As Integer
I have done all the computation and final output was in the form of tables with different solution sets in one worksheet in an excel.
From the dropdown list (List of solution models), when I select one solution set it should pick that particular workout and populate the final output table in the new worksheet in the same excel. Firstly, I need to establish dynamic linkage between the drop down list and final output tables and then push the final table to new worksheet based on the option selected.
I need to make a cell display the contents of the cell immediately below it, regardless of if there are rows inserted at the referenced row or above or below it on the worksheet. ALSO I need to do this at several additional cell locations down the worksheet. Such as : A1 displays A2, A4 displays A5, A7 displays A8 etc.
Example: I want A1 to display whatever is in the cell immediately below it. In this case A2. I need to be able to insert several rows at row 2 and have whatever new value is now in the A2 position displayed in A1. After the rows are inserted I need the cell that was in position A4 to continue to display the contents of the cell below it.
I tried using the formula in A1 of: =INDIRECT("A2") and it works good except when I insert the rows my similar formulas below the area where the rows were inserted continue to refer to the specific original cell and not the one positioned now below it.
I had 4 initial temperature values and after some time i got new temperature values. Now for calculating 2nd iteration i need to use new calculated values and for third iteration values from 2nd iteration is to be used and so on.
How to calculate temperature values directly for 10th iteration without solving each iteration?
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.
I was wondering if the solver was the only way to solve implicit equations. I am looking for something that will automatically solve an implicit equation after the appropriate information is entered into the referenced cells.....
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.
I'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.
I 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)]
I need to automate the attached as per the following (by not recording macro unfortunately).
Sheet one has a dump of data. First, I need to change the data format from yyyymmdd to dd/mm/yyyy. Then I need to filter for region EU and only copy the filtered data from columns A, C-D, F and the difference from columns I-J to Sheet 2. Then in Sheet 2, I need another column to calculate the difference per unit.
Any way to exclude colored cells from addition in a column. I will attach a simple example document.
I am building a spreadsheet to keep track of my monthly spending, and debt balance. I keep track of the total amount of bills I pay each month. As I pay them, their respective line is highlighted green in the spreadsheet. I would like to create a macro/formula which would sum the remaining cells in the column which are not highlighted to display the remaining monies which need to be paid out. I'm not sure if this matters but I am using office 2010.
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):
