Hi!I need some help with programming. I will give an example with the help of candy. The end result is depending on the flavour of the candy and classification (say quality class) of the candy. The user make different choices by clicking in list boxes. The number of alternatives in the boxes is displayed here as ["x" alternatives]"Choice1"The thing is the candy starts of in Class4 if it's not supposed to last longer than 1 week. If it should last longer it's increased with two classes. [2 alternatives]"Choice2"The second thing is the shape of the candy. If it is a flat candy it gets reduced with one class, otherwise there is no reduction. [2 alternatives]"Choice3"The third thing is the content. If it consists of allergic ingredients it gets reduced with one class. Otherwise there is no reduction. [2 alternatives]"Choice4"The fourth thing is the size (6 sizes): Size = 1,2,3,4,5 and 6 [6 alternatives]"Choice5"The fifth thing is the flavour (7 flavours) Flavour 1,2,3,4,5,6,7 [7 alte
Dear All,I was working quite happily in a Mathcad sheet, and went to open an earlier version of the same sheet at which point MC 'stopped working'. Now, whenever I try to open either of these files, or a file that has them as references, Mathcad 'stops working' It does however open other files. I assume that these two files have become damaged or corrupted, but would really like not to lose them. Does anyone have any solutions for recovering these?ThanksFrank
So I'm working through finding some values for a thrust vector and I desperately need to figure out this equation could someone help? I need to solve for the end mach.
Can i make a IF statement for my references? Say if true reference1 is active, and if false, reference2 is active.If not, can i perhaps use VB for programming it?Thanks!
Hello,I have Mathcad Prime 4.0 and would like to work with a dollar sign versus the little square symbol (see below). It seems possible in earlier versions of Mathcad but I can't figure it out. Any suggestions?Thanks,Adrian
Hello. I am trying to draw two curves: the average voltage and the root mean square voltage in the function of x1. When x1 = 0..pi and x2 = pi. I am running into problems when defining the lower limit of the integral since I can't seem to define it as a range variable.Here is where I have got done:eThank you for your time. I really appreciate any help
So today's challenge...So I have a problem to which I am given the answer. The real issue is that I need to understand how the answer is derived.I have attached a word document which gives the problem and the solution. I understand the first steps taken in that the resultant forces have to be at equilibrium as the block immersed (and floating) in the 2 liquids is at rest. i.e Then by factoring g and A out of the RHS and dividing both sides by gA I am left with: Then as the question calls for the ratio h1/h2, I believe that I multiply out the LHS then divide both terms on both sides by h2 to get:I know that the example in the question factors the LHS but I don't believe this is necessary. The problem I am then having is that the question's given answer in the attached document seems to suggest the ultimate answer is:however, from everything I have tried algebraically by hand, the likes of Cymath / wolfgram Alpha and Mathcad itself the answer is suggested to be:Am I going mad somewhere o
Is it a bug or is there any reasonable explanation for this effect?I am aware of the different ways that third root of x and x^(1/3) are implemented for negative argumentsand those negative values sure are the reason for the error because all works OK when I "assume, x>0". Nevertheless I don't clearly see a reason why the symbolical evaluation after der derivative should make the numerics fail.
Hi! How can I define a second variable based on a previously calculated one? I calculated X and I'd like to define Y as equal to X, but I can't do it with a simple equal sign. I had to write a Given function for it.
I have a very basic question. the for loop example in programming tutorial task 3-1 for prime 3.1 does not work as stated. What is wrong?
When i input "+..+" , it appears two gray block, and i will also display in printed pdf files, it is not beauty.How to input ".."correctly in 1^2+2^2+..+n^2 or a^2+b^2+..+z^2. etc ( without gray blocks)?
CAn anyone tell me if it is possible to have multiple values for a given worksheet? I.e. if I want to work on multiple problems in one worksheet can I assign different values to the same variable I.e very simply can I calculate one rectangle area L*W using L:5 and W:5 then a differing rectangle of L:10 and W:10 without having to define as L and L1 and W and W1?CheersA
Can anyone tell me how to define for example x/y as a value I.e 1? This is in context of a ratio. So I'm looking to define a ratio so that when I insert it in a formula MathCAD knows what the ratio value is? WHen hen for example I write x/y I'm not allowed to define this I.e pressing : does nothing.Cheers A
Hi,When calling the Help Function in MathCad Prime 3.1 or MathCad Prime 4.0 i get the error Message:I'm working with Windows 10 and Java is still up to date.Has anybody an idea?Thank youregards, Volker
I try to find the derivative of u.somehow i not clear with the meaning of this equation.can someone explain to me? thanks in advanced.kindly refer to attached mathcad15 file.
Dear all,I want to draw 3D plot for my mathcad program by considering,x-axis ---> xy-axis ---> f(x)z-axis ---> vI attached my code below.
When I have a while loop that goes as long as x does not equal 1.0, then it does the operation x = x + .1. The result is an infinite while loop. Why does this happen
I am trying to use the Given - Find Solve Block to determine the embedded length for a circular pile foundation given in an ASCE article, "Resistance to Overturning of Single, Short Piles", E. Czerniak, Journal of the Structural Division, Paper 1188. The attached worksheet contains an equation for the required length for a given pile diameter with a set of lateral and vertical loads. Any comments on why the error message resulting from the Find(L) statement would be appreciated.
I want to use MathCAD Prime as a Formula Derivation Worksheet, and record the process like the picture below( just for example 😞I have three problems:how to remove the red square in a:=n? (it will display when printing)how to remove the gray block in left side of =?how to use square brackets outside the Parentheses?I think it is convenient to do Formula Derivation and record it in MathCAD Prime, do you have a better software or tools?
Dear all,I have been trying to do a cubic spline for on a mechanical spectral response. Unfortunately the spline does not work, can anyone explain to me why is this happening?I have used it in the past many times, without any problems(different data).Is there a easy solution for this ?Cheers to all!João
Hello, new at using Mathlab 14, I have a problem with unwanted variable's value change based on it's location on the worksheet. In the attached file, variable's K33,5 value changes by moving it above/below worksheet's first horizontal line and I cannot understand why. Help needed.
Dear All,I am again coming to you with an issue I have related to work I am doing from a text book this time on the topic of integration as summation. The text book is trying to prove that integration is essentially the summation of an infinite number of rectangles. I have inserted images of the text in question as this is easier (sorry for this being sideways).The example looks at a simple graph of y=x as seen in the below images. The problem I am having is I understand the concept, indeed I know that to find the area under the line y=x can be derived algebraically by integrating x to give x^2/2 and calculating for x=4 and x=2 and taking one from the other to get an area of 6 units^2.However, following the example in the text book in the second image I can't see how the penultimate line of lim n to infin 4/n *n + lim n to infin 4/n^2*n(n+1)/2 gives 4 + 2 = 6. I can see that 4/n*n will give 4 as the ns cancel but on the other side I see that 4/n^2*n(n+1)/2 should give 4n^2+n/2n^2 would
Has anyone developed a touchstone file reader subroutine for Mathcad?
Hello Everyone. From : Need help plotting the intersection points. Thanks in advance for your time and help. Best Regards.
Shift+space key conflict with Windows 10 system input method editor when edit table in Chinese Simplified version Operation system.problem:I want to insert a column in table, when i press Shift+space key, table doesn't has any change, but Windows 10 system input method editor change from half characters to full characters.Like the picture below : problem solution:install a new English language to system, when you want to add a new column to table, change the language from local language to English.Request:Could PTC MathCAD engineering team change the hot key "shift+space" to others or add switch options?
