HiHow can I use if function when I have two statement shall be valid at the same time:For example:y=0 if x=5 and z=10y=1 otherwiseHow can I replace "and"?Thanks

Can anyone help on how to use the matrix (taken from an excel file) in the equations...?In the attached Mathcad file you can see that I need to evaluate the output power equation as a function of k (as highlighted in yellow in the last page).I need the matrix (L11, L22, k etc) to be used in the equation (for the variable k)...In short, I need to plot a graph Pout(k) vs k........ all the values indicated in the equation of Pout(k) must be taken from the matrix.. please help to get the plot

Some time ago, there was a problem with the use of "Given-Find" solve block (I can not find this theme in forum). In an attachment, you can find a document with a solution to this problem from the PTC's technical support.

Hello,on the left side of my mathcad sheet is a pdf copy past shots. on the right side i am trying to follow the same steps. please scroll down to the red arrow. i am not sure why the results on the right side does not match what is the screen shot on the left side for Ke1,Ke2,Ke3. the other two red arrows are below. Thanks!

This is as much a tutorial as a problem, I suppose.  When I was teaching dynamics I would take a representative problem and "beat it to death" to illustrate not only the dynamic priciples but also how these problems can be worked efficently using Mathcad. 

Hi all,I tried to use two equations to solve two unknowns, but it said cannot find answer because needing at least two arguments that is applied to 1.I don't understand what that means. I have attached the worksheet and looking forward to hearing your solutions.thanks

Hi, All --I am trying to use spherical harmonics to represent a surface in 3D. The worksheet calculates through without error, but the results are off by ~24 orders of magnitude (for 12th degree Legendre polynomials). I note also that the magnitude of the answer increases with the degree of the polynomials.Anybody have any ideas? Maybe there's a better way to approach this altogether?Thanks in advance.Matt

why it is not possible to work in Mathcad (Prime 2.0) with the Newton Noation? As an engineer, I often need a point over a letter. Typically, the mass flow is indicated by a dot above the m and the flow rate to a point on the V. Are there not many people who need such a thing? Does anyone know a viable workaround?

HiI use the match function to find a value in a vector. However, for some values the match function returns a matrix instead of a scalar, see picture. Why does this happen? What is the match function doing?

For some reason, the square root symbol works but raising to a power of 0.5 doesn't:Version: 15.0Mathcad doc attached.

Hello people,I use Mathcad for college, and its a very usefull program.About a week ago Tab "Math Formatting" is normal, but don't update sheet, see example:I Start a new, then Tab Math Formatting, and choose like in piccture.When i start make calculations, it never respect new Formatting. I already have "repair", "uninstall" and "install" again.One use is complex numbers, i choos to show in polar degrees, and it shows in rectangular, why?Anyone has the same problem and was able to fix it?Regards,Luis Lourenço,Portugal

Hi all,Could anyone help me find what problem within the calculation, To solve two variables using two equations, but it finally said there needs at least two arguments but is applied to 1, what's that mean?

can you change text based on a formula without using the if statment.for example.sf = if(design = LRFD, "resistance factor", "shear factor"Can the above be done by another method?maybe programmingThanks

I need to modify programming codePlease. See the attachment file

Almost there guys.I've manage to draw the shear force diagram from some given numbers, I'm now trying to plot the bending moment diagram but for some reason I'm getting an error on the moment axis.any suggestions or assistance would be greatly appreciated.

Hi - see attached.I'd like to show OOB with units of gram-millimeters (g.mm).When I change the units from m.kg to g.mm it adds kg.s^2/m.Can this be avoided?

I'd like to type something like this:Area = a x bwhere:a := 10b := 20Thus,Area = 200How close can I get in Mathcad?I've tried using the boolean "=" for the first statement but then can't get the last statement to work.

I'd like to show my working, is there anyway to make the last line work itself out automatically:E = stress / strainstress = F / Asubstituting and re-arranging:strain = F / (A.E)

Hi all, I am a new user to Mathcad and I have came up against a very tough problem. In the attachment (and image below) there is a table that looks up a value of Cy for a given K and M simple. The problem comes when the values for K and M are not a whole numbers for example - K=32 and M=0.23 then the value for Cy is in the range of 1.63 - 2.3. You need to interpolate between the four figures. Cy will actually equal - 1.7348I am looking to produce a Mathcad function that would allow me to look up any value of K and M. You help is much appreciated.Kind RegardsChris.

MathCad Prime is still useless and MathCad is clearly no longer being significantly supported. I need to reconfigure my license every few months. This time, it doesn't seem to work at all. I am pretty much terrified that I will lose all of my work of thousands of hours on MathCad (the legitimate versions of the past). Has anyone found a legitimate program alternative to MathCad 15.0? MathCad Prime is not worthwhile. Does anyone have any suggestions on what can work to recover all of that work without completely regenerating it? Thanks, Bill

Hello,I'm trying to 3D plot a solid defined by the X,Z coordinates and a constant for the width (Y). I am using the surface type to create a filled surface for each side of the shape. I am able to create most of the surfaces, but cannot figure out how to "fill in" the front and back faces.I have been searching the forums and have found examples of this, but none have shown a surface with more than four points, which I believe may be an limiting factor. I have tried numerous methods of how to arrange the matrix, but my understanding of the matrix structure required for the surface plot is limited.Please see attached worksheet.Thanks!

How does Mathcad handle sin and cos, appearantly Intels implementaion has its limitations...https://software.intel.com/en-us/forums/topic/289702On Linesin(36001)= 0.01745241MathcadExcel0,01745240643728350so not really relevant but better than Excel?Could be depending on the FU or GPU used, juts in case...regards
