Hi,I am having an issue where I can't get a range of values when I use two ranges in one equation: for hlc I am expecting a range similar to Le and v, what am I doing wrong? Thanks!  

Hello everyone, Someone knows a smarter way to draw an equilateral triangle? Thank you very much.  

Hello, dear Mathcad community!    I am working with 18 equations and I need to get the result of 18 unknowns symbolically.  I have searched through the PTC community and tutorials, but Mathcad is telling me about the error with undefined parameter in the function. Can you please help to figure that out? And is it possible to solve such many equations symbolically in Prime 3.1?

How to factorize the number by using solve block?

I had one bad mark on my math exam at school. The question was - what is the sine of 45 degrees. I immediately drew a rectangular triangle with single legs in my head and gave the answer - one divided by the root of two: the leg divided by the hypotenuse. But I heard from the teacher that the answer is wrong. The correct answer is the root of two divided by two: this is how it is written in all textbooks! And, actually, why?

Hi everyone,   I'm a newcomer to MathCAD and am stuck on a problem.   I have a vector V with n number of data and I want reduce it into a new vector V' in which the first row is the average of the values of first 70 rows from the vector V, then the next row in V' is the average of the values of next set of 70 rows in V, and so forth. I've written the problem more clearly bellow: I'm really not sure how to tackle this, so I'd be thankful for any input. Thank you in advance! Tea

Dear all  Please help me do summing data depending on Index as attachment. Thank you

Hello, I have a beam with a triangular line load. For this task I wanted to visualize the existing Mb curve using a My curve. I created this with partial functions. So far so good. As a further step in my task, I wanted to use Mathcad 15.0 to determine the location of the greatest bending moment. From a purely mathematical point of view, this corresponds to zeroing the 1st derivative (lateral force). Everything is clear from the logical understanding to the procedure. Unfortunately, from this point on it does not work completely smoothly and without problems. Because I have created a new definition with the derivation and function including the run variable specified for the derivation. Then I wanted to use the symbolic commands "Coefficients" to output the existing values ​​and to have the 2 possible zeros displayed again with the additional "Set to zero" function. Unfortunately, when performing these steps, I always get the error message that there is "more than one independent varia

I'm trying to create a calc where the answer is a design factor. The calc works fine when just using numbers, but when I try to use a value from earlier in the sheet I get the 'units are not compatible message'. Would appreciate any help on this, thanks.

As most of the more experienced users of this board will recall, I am a very long-time user of Mathcad (I think it goes back to Mathcad 4!). You may also recall my significant reluctance to use and/or deploy Mathcad Prime...of any version to date, for the countless reasons we've all shared here. Even given this history, I am to a point where the topic has arisen within my division & company to consider deployment of Mathcad Prime ("Why haven't we moved to the newest version?"). Through all of this, I have given kudos to PTC for a number of advantages from newer features within the Prime family (yes there are some very nice capabilities we don't have in v15). Because of the continued, significant need to keep a foot heavily planted in Mathcad v15 world along with now a desire to begin considering a migration to (or inclusion of) Prime, I'd like to know if anybody has deployed BOTH codes to their community. If you have, how have you accomplished this? Was it worth it (i.e. would

Hello, I am struggling in implementing a problem that  implements Newton's method to solve a system of two non-linear equations: 𝑥^4−𝑦𝑥^3=1 6cos(𝑥+1)−𝑦=2 I am trying to implement  𝑥^(𝑛+1)=𝑥^(𝑛)−𝐽(𝑥(𝑛))−1∙𝐹(𝑥^(𝑛))with 𝐽(𝑥^(𝑛))^−1is the evaluation of the inverse of the Jacobian matrix and 𝐹(𝑥(𝑛))is the output of the equations. I have done most of the iteration work I believe in the function but I am stuck on how to manipulate the values to come up with the intersection points of these two functions.   Here is my code:

I am a wxMaxima user and shifted to Mathcad recently on the suggestion of my friend. I am testing the software and am being amazed by the easiness. But I found its symbolic engine not up to the mark (let's delay this discussion for some other post). Currently, I am testing the plotting feature of Mathcad. It has become my habit to test every new software I use with these commands just to see the beauty of math and the power of that software.  I am not able to figure out the way from the online help available about this topic and therefore am asking in this community forum.   The first animated plot that I want to create is of a spring moving. The wxMaxima code for this is shown below. This creates a 3D plot of a spring that is stretching and expanding.   The second animated plot that I want to create is a vibrating sheet. The wxMaxima code for this is shown below. The animated gif is shown below. Please also mention the method in which 2D plots can be animated. Also,

Hi.   I work for a small employer and the company only has Mathcad 15. I'd like to be able to go back and forth using the same file between the version of mathcad I have at work and the version I'm considering to purchase for my personal home use.   Can mathcad 15 files work with mathcad prime 6.0 and vice versa?    Can mathcad 15 still be purchased individually from reliable sources?   Thanks!    

To all In mcad Roark's e-book 6th edition there is a worksheet to calculate the stress concentration (case 17b). I just noted that the constants to calculate the values for C1, etc are different to the ones in the latest book (Petersons 3rd edition) 1. Am I correct? 2. I cannot find a 1974 copy 1st edition (I guess!)  which appear to be the reference used. Has anyone got access and could confirm? 3. Is it the same in the latest ebook which I think is based on Roark's 7th edition but as far as I can tell in the printed Roark's 7th edition the numbers are from the 1974 edition too   Thanks Regards

Is mathcad express free trial compatible to MAC OS?

Hello,How can I insert or add new special characters in Mathcad?How can this be done?For example to extend the greek tab with the hat character, but also others.   For example, I would like to add the following character - hat: ???Thank you.Best regards.  

Hi, I have problem with printing name (types inner inserts) from tables (values picture). I have 2 values which are not in tables: N.Ed=31kN and V.Ed=35kN and then analogues/relatives values from tables N.Rd and V.Rd in columns. So i need to print all names from (vakuankkuri) column which are meet the conditions:  ~N.Rd>N.Ed/2 and V.Rd>V.Ed/2   I have already ideas with matrix (picture matrix tables) but don't know how to solve this problem by right programming/looping. Thanks for advices.

Hello,I have a quick question.I am using the MINIMIZE and MAXIMIZE function, to find parameters value that optimize a funciton.I am wondering how I can set the solver to find the GLOBAL max or min of the function, or to set to give me LOCAL max or min.Is that possible?Thank you in advanceRegards

Hello, dear Mathcad community!    A am working on a suspension kinematics problem and I am trying to solve the nonlinear system of 18 equations with 18 unknowns. I have tried to solve it using the solve block, but I have an error that underlines the whole Find(...) function and says: "This value must be a function". Can you please help me to figure out the problem? I am kind of new to Mathcad and I was trying to do everything like in tutorials 😃

I want to solve the symbolic answers. Prime 6 sheet attached.

Dear all,   i would like to evaluate an imported matrix from excel. My Prime 3.0 sheet is attached.   Basically what I have: I create a lookup table in mathcad where every row represents a  component, in this case a MOSFET. Every column represents the corresponding parameters of the component. I can evaluate row by row with any equation. By doing this I can obtain for example as a result an array, for example an array with the calculated losses for each MOSFET. So far so good.   What I need: Now I need some kind of programming or searching command in mathcad, where I can find all the indicies of lets say an for which a special searching condition = true.   For example my result array:   Losses = [100mW, 100mW, 70mW, 80mW, 100mW]   The goal is to find all indizies where Losses < 100mW = true .   Now the imported excel matrix can be quite large and confusing. With the indizies, which were obtained before, I want to edit the imported excel matrix

Hi, I am new in Mathcad with a little experience. I would like to learn about the Scriptable objects in Mathcad 15. I hope it will not only help me to learn the automation but also sharpen my Mathcad skills. Since I am very naïve in the programming skills, I would highly appreciate if you provide to some good references/books to learn the Visual basics which will directly help me to do some work on the scriptable objects. Many thanks S
