Using IF With Larger Equations, If Value = 9 Then Display "0"?
Jan 13, 2009
I 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)])

y = 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.

I 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?

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.....

I have three different equations i am trying to combine to one line so I do not have to use three columns.
Equation 1.
If recommend quantity is < 100, and the Number of times part number used is one, then Recomnend quantity was used
Ex =IF(F277 100 and the Number of times part number used is greater then one and less then 10, then Recommend quantity was used
Ex =IF(G277100,*and(E277>1),F277*2.0)

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}
Often there will be many more than four terms...

I 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
SolverOk MaxMinVal:=1, ByChange:= Range("V34:V36")
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.

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 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.

I have two cells with the following equations:
H3=IFERROR(VLOOKUP(A3&TEXT($A$1,"m/d/yyyy"),'CLABSI_Raw'!$A$1:$M$300,13,FALSE)," ")
I3=IFERROR(VLOOKUP(A3&TEXT($A$1,"m/d/yyyy"),'CLABSI_Raw'!$A$1:$M$300,10,FALSE)," ")
In an adjacent cell, I am trying to use an if statement
J3=if(and(H3<1,I3<1),"yes","no")
I am not getting a return in cell J3.

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 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.

I had a question about adding numbers, sort of like algebra equations (best description I can think of) into a spread sheet. Example:
Cell A1: 8
Cell A2: 8l
Cell A3: 8ls
Cell A4: 8l
Cell A5: 8
Cell A6: -where I want the total to be displayed in the following way: 16+16l+8l
Is this even possible to calculate by grouping like numbers?

I have the following data
A1 - 65.23
A2 - 1923.52
A3 - 945.18
A4 - 182.54
In column B
B1 =exp(A1)
B4 =exp(A4)
both are fine, however
B2 =exp(A2) - it is showing #NUM
B3 =exp(A3) - it is showing #NUM
Same case for all larger numbers

I have Excel file A with a full list of IDs that were selected to take part in a study - about 5000 IDs with only one field "ID". I also have Excel file B with about 1500 ID of people from file A BUT who already took part in the study. Now what I need to do is filter out from file A all the people in file B so in file A I am only left with those who didn't take part.

I'm having some problems sorting a list of numbers that some are larger than others, but it would sort it by how large the number is in regards to 123 or 45... 45 would go first instead of 123... I tried to change the column to numbers but it still won't work. as well as in the custom sort section. I'll try to upload a sample...

I have a macro that should be exceptionally simple and works fine up until the point where I try to use an If statement with a conditional.
I have run the macro up to the If statement, at which point FinalRow is 40 and StartRow is 6, so the If statement below should run but it doesn't. I've had this problem before and just given up, the only thing I can think of is that the If statement only compares the first digit in the String.
I've only copied a small part of the code as I don't think the rest is relevant and just muddies the page but I can paste the rest if needs be...

I am currently using the following formula:
=SUMPRODUCT(('Step 1_Data_Current Qtr'!T2:T10000=B2)*('Step 1_Data_Current Qtr'!C2:C10000<>"")*1)
...to count the number of instances in a data set where:
T2:T10000=B2 is counting records where the value in the cell is set to B2
and
C2:C10000<>"" is counting records where the value in the cell is not blank.
The current formular is working, but I want to change the formula so that the values in C2:C10000 is looking up specific names (in this case, physicians) and not just where the field is not blank. How can I change to lookup physicians in a specific list that may change, located in a separate tab from the main data set?
