This turned out to be at least one of the six correct values for T, as I plugged it into the equation with my calculator and saw the equation multiplied out very close to 1.89.

However, I am not sure how to set things up to solve for six correct solutions in Excel!Īlso, using Solver and setting D2 as the objective (to a value of 1.89, by changing variable cell B4), I got an answer of T = 1.256897 s. I assume that multiple correct values in this case is simply due to the oscillating nature of the cosine function. "Step 3: Determine six correct periods and submit the complete spreadsheet with six correct answers included to the instructor." Thanks, Phillip, for your very helpful reply! However, I forgot to mention my assignment states that there are actually six correct answers for this equation.
Thanks a million for your help with this problem I couldn't survive without it! Also attached is the worksheet from my physics class that asks me to do this problem with Excel (note that it is the 2nd of the two problems given in the two page worksheet).
That is why I am now asking the experts!Īttached to this message is a link to my current worksheet on Excel for this problem, so you can tell me what I am doing wrong and need to rearrange. I am sure that there is a way to set things up in Excel so as to make it possible for me to solve this problem and find a value for the period of oscillation. Unless I have a definite value or direct expression for T, it displays a message that I am committing a division by zero error, since the unknown T is divided by twice in the equation The problem is that when I plug this equation into Excel, I cannot seem to find any way to solve for T unless I actually have one of the boxes set for T= something. It uses the following built-in Excel spreadsheet functions: MMULT (), MINVERSE () and TRANSPOSE (). My text tells me not to "waste time trying to rearrange this equation for the variable of interest (T)" and this equation is so complex that I quite frankly could not figure out how to arrange this equation as "T= everything else" anyway. The size of the system is programmable by the user from 2 to 20 which means, depending on the setting selection, the model can instantly find the solution of linear systems starting from 2 equations and 2 unknowns up to 20 equations and 20 unknowns. I need to solve for T, which will describe the period of oscillation in seconds. The values of t (3.45 seconds), of a (1.89 m/s^2), and of A (2.34 m) are given. The equation is a(t)=-A(2pi/T)^2 times (cos(2pi/T)(t)), where a is acceleration, t is time, A is amplitude, and T is the period of oscillation. I am currently trying to solve a problem in a physics class in which I am required to use Excel to solve for an unknown variable in the equation for acceleration of an object in simple harmonic motion. The Scope column tells you the scope of that named variable.Hello, my name is Stephen Lanford and I am very new to using Microsoft Excel. The current value is displayed under “Value.” You can find the reference cell in the “Refers To” column. There you’ll see all the cells that have been assigned a name. Go to the Formulas tab and select Name Manager. Enter the name of the variable in the dialog that comes up.Click on the Formulas menu item, and choose Names (Excel 2003 and earlier) or Name Manager (Excel 2007 and Excel 2010).Select the cell with the result that you want to declare as a variable.In the Add-Ins available box, select the Solver Add-in check box, and then click OK.Click Add-Ins, and then in the Manage box, select Excel Add-ins.In Excel 2010 and later, go to File > Options.
