Mathcad

I have two ode's that have a parameter. When I set the parameter to zero some (but not all) the solvers give results that might be reasonable. But, if I make that parameter a very small number, none of the solvers work even though this would not seem to make the equations parthological. Does anyone have some insight to what is going on? Thanks.

I encounter the wrong output of the calculation.Equation[x y z] := [x=A, y=x, z=sqrt(x)]T --> solve,x,y,z,Of course sqrt is input as mathematical root actually.The output becomes;[A A 0]The z value is wrong.How can I fix this?

I wrote the program which fit two datasets by the same ODESOLVE and miner. But I call the function twice and the program works slow.  So anyone knows how to make it faster to fit two datasets?    

I'd like to suggest vectorizing the functions num2str and str2num.        I've had to write vectorized versions of these two functions to allow me to evaluate array expressions as arguments (I can't explicitly vectorize over num2str or str2num when using such expressions).     What evaluation reasons might there be that would mitigate against vectorizing these functions?   Stuart

Today marks the 200th anniversary of the birth of the great writer Fyodor Dostoevsky - Wikipedia In my book 2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com) I have solved (with Mathcad of cource) one problem from one Dostoevsky novel. Do you know this novel? Do you know this problem? What Dostoevsky novels do you know? What Dostoevsky's novels have you read?

Hello everyone!I would like to draw the attached graph in 3D with Mathcad 15. It seems to me that this problem has already been addressed in the community but I cannot find it. In fact, it is a rather arduous job although from the geometric point of view it is a question of tracing flat surfaces orthogonal two by two. To do this, I downloaded and installed "images14.exe" and also the list of the functions contained, but I don't know how to use it. How can I avoid using these functions? Could anyone help me? I thank him infinitely.

We are obliged to use only SI when writing textbooks, reference books, articles, technical reports atc. And in this system there are no units of information. How to solve this problem? That's how!

Can't find where to download and install Mathcad Prime 6.0. I received the license from my university.

In my entire life, I only wrote once Mathcad-sheet with ORIGIN not 0 and not 1. Questions. Do you have own Mathcad-sheet with ORIGIN not 0 or 1? What ORIGIN was in my Mathcad-sheet? What is it this my Mathcad-sheet? You can find it here 2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com)

In Russia, Roman numbers are used even by not very literate people. One example.The log house needs to be moved to a new location. Before disassembling it, the logs are numbered in Roman, not Arabic numbers.   Do you know why? Choose please the correct answer! 1 The carpenter wants to show his high culture - knowledge of antiquity! 2 The carpenter cannot count, but he has a clock with Roman numerals on his left hand. He looks at them and numbers the logs. 3  People who are assembling this house in a new place may not know Roman numbers. But such a program will help them! But this program has a small defect. Can you find it and fix it?

It will good to have in Mathcad new temperature units. Allen Razdow will be glad!

Hello everyone. I tried to solve the equation with several solutions. Probably the solution given by Mathcad 15 is correct. However, the Prime7 method of entering equations in a matrix does not give a solution, and the Solve Block method gives a numeric value, which is probably incorrect. I attached these files. Please advise.

I'm having difficulty opening Mathcad Express 7.0.0. It's been on my computer for 30 days, and now when I click on the app to start it, it starts up, but when I click on the app to bring it up, it wont open the screen.

There is an old philosophical parable about how one user was waiting for a new Mathcad for a long time and rebuked PTC, telling the company that the Lord God created the world in seven days, and PTC was busy with Mathcad Prime for a whole year. PTC was not at a loss and answered like this: "Look at this World and look at Mathcad!"
