I converted a Mathcad 15 file to Prime 4.0, and one of my 3D graph cannot be plotted in Prime 4.0, the message says: "the number of plotted points must be below 40,000".the only difference between the plot in Mathcad and Prime 4.0 is that, that I converted the one from Mathcad to Prime 4.0the one in Mathcad 15 looks just fine.Regards,Rogelio

Hi all,I am getting an error as all evaluations resulted in either an error or a complex resultwhen I try plot a 2D graph in which,x-axis ranges from 0.01 to 1y-axis is logarithmic.I attached my code below.Could you please tell me how to overcome this error ?y-axis must be logarithmic and x-axis is normal values ranging from 0.01 to 1.

Hi Everyonecan anybody help me about the problem in attached sheet?When Mathcad knows "X"is foot why it says this variable unit is not compatible and does not do the rest of calculation ?Thanks in advanceRamak-KSP ENG

I would like to generate many plots using a range of different parameter values. I did 10 in the attached document manually using Quickplot. Is there a way to do this more efficiently especially if I would like to look at a larger number of plots? Thanks for any help.

Hello everyone !For the cubic equation with real coeffs there are Cardano relations to find out roots. Or the use of trigonometric substitution.Do you know similar formulas for the case of complex coefficients ?Google is pointing to a paper in Soviet (now : Russian) Journal of Numerical Analysis & Mathematical Modelling, vol. 4(1991)/uncertain year/ (No. 2), p.315, which is out of my reach for the time being. Thank you & best regards, Liv.

Quien podría convertir un archivo de mathcad 15 a prime 3.0 ya que no puedo lograrlo,

I am trying to ingrate the moment of a beam to determine the displacement of the beam. I am have a hard time getting the evaluation of the displacement to calculate. Can anyone tell me why it takes several hours for the program to calculate the displacement on page 5? Is there a ways to make the calculation quicker? I am using mathcad 15.

MathCAD is too good. It's doing more than I really want it to do, particularly with some units.Today's problem is the pound force. MathCAD knows the definition of the pound force, and the problem is that when I want to keep something as a pound force, it instead inserts the definition of the pound force and cancels out everything that can be cancelled out. When I try multiplying out by the unit I want, it still does the same thing.I'm trying to use the spring constant k in my US standard formulae. Normally, k=force/distance, or lbf/ft. Since the definition of the pound-force includes feet (I think it's something like ft*lb/s^2), then MathCAD automatically cancels out the feet and leaves me with s^2/lb, which makes no sense in the context of what I'm trying to do.How can I get MathCAD to just mind its own business and leave lbm as lbm? I can't seem to find a way to redefine the built-in lbm and I'm not certain I want to do that anyways.(I understand that this sort of topic is well-discu

I downloaded 4.0 express and turned on the 30 day full version trial.  (Because it will probably take IT a month to upgrade our license server).  The good:- It's released.- When I print or pdf, collapsible areas don't seem to shift to the left anymore.  I still lose the left edge of the box, but that's still a vast improvement.  - Occasionally I couldn't label a constant a constant to get it's font to change to accordingly.  It still just showed as a variable.  That seems to be resolved.- When i switch between tabs it seems to remember where it's at.  Before it would always jump back up to the top.- Protected areas.  Probably my favorite upgrade. - OLE.  useful but not really crucial.- Line breaking.  But see my exception below. - Occassionally 3.1 would freeze and I'd have to click a separate window for it to regain it's brain.  So far I haven't seen that.  (But I'll keep looking as it's intermittent)The bad:The following bug

Hello sir,I have a big issue with the attached mathcad file, I tried to open it several times but as soon as it open it closes againPlease if some one could help me to open this important fileI appreciate your assistance

Nothing to do with Mathcad, but I know some of you enjoy a good challenge.  And I'm stumped.  Here's the situation:  Two circles of different diameters, one vertically offset a distance e from the other.  Vanes of thickness t are centered in the smaller circle.  The vane are 90 degrees from each other.  What are the top and bottom colored areas?  I'll gladly take any hints on how you'd do it.Thanks!

Hello,I want to calculate dynamic deflection of the worm in a worm drive. The formula given in my book does not seem to work in Mathcad Prime 3.0.In the book there is no multiplier (*) printed after tan^2 and cos^2. There is just empty space. I did change the formula around in all kinds of ways.I put tan inside parenthesis like (tan)^2, or (tan^2*(gamma+Q)), or (tan(gamma+Q)^2) but nothing works.What do I do wrong?Thanks maurits

HiI have one small problem with Mathcad plots. Mathcad plots my function only in part of it insted of filling whole XY plane. I attach my mathcad file as an example. What can I do for the plot to be bigger?

When I load a matrix up with al reals the |A| or det(A) works fine and returns the value.  If I add a +1i or any imaginary number to an element, the |A| or det(A) returnb 0.  This frustrating since I have programs that use this alot for filling arrays in a linear systems problem. 

The menu items under the Math / Regions are all grayed out. Is this the correct behaviour?

Hello, dear community!I am trying to solve issue with MathCad and stuck. It is calculate wrong and I dont know why.If someone could help me, i will be very grateful!See attached spreadsheet.Best Regards,Aidan

Hi, I need assistance debugging a program to build  a Z-score table with the intention to reproduce in Mathcad a z-score table very similar to the one that we could create with an excel spreadsheet. This just for fun!See attached files.Thank youjuan

Attached are the Mathcad 14-15 worksheet and input data file used to generate the "Transit of Venus 2012 June 5-6" animation (video) that I posted on February 2, 2012. This is an astronomically rigorous calculation based upon accurate geocentric ephemerides of the Sun and Venus. If you have not heard about this astronomical event elsewhere, surely you will, for two reasons! Because (1) this is the last transit of the Sun by Venus that anyone now living is likely to ever see. The next pair of Venus transits will occur on 2117 December 11 and on 2125 December 8. And (2) it will be easy to observe (weather permitting) as well as rare. All you will need is an inexpensive pair of "eclipse glasses," or you can construct a "pinhole camera." But telescopic observation is also possible, with a full-aperture solar filter. So check out the worksheet and video and be watching your local news media as we approach the month of June 2012. CAUTION: Never look directly at the disk of the Sun without ap

Hello,I would like to know if it is possible to calculate a derivative of an array in Mathcad without fitting a function to the data set. A have an expression of a form: sigma(x,y):=A*F,x(x,y), where A is a constant, and F(x,y) is a function of x and y which is defined with a data set/array (data imported from Finite Element Analysis). I would like to calculate a derivative of F(x,y) with respect to x.   Best regardsRafal
