o     answer was supposed to 0.274 and 0.052

  Do i have to use y1 when i sove ode or not?

could you help me?

Do you know it?

I am attempting to complete a comparison using values from a table and am getting a scalar value error. What do I need to do in order to get a column of values out of the attached.     

I have just renewed my license for Prime 5.0 and when I looked for updates saw that Prime 6.0 is due out September 15, 2019. Does anyone have any info on if this will happen?

Hi, A friend asked me for a phase diagram of a transfer function (see photo and file). I distractedly used the arg(Im(W (iω))/Re(W(iω))) operator for the phase graph. I know this is an old problem, this graph was actually incorrect as seen from the comparison with the correct graph of the function φ1. Why does this happen?

In some of my worksheets, there is a lot of space dedicated to the text. Although I use the "Times New Roman" fonts, it happens that after closing the file and then reopening it, I find the fonts changed to "Arial". Can anything be done to stop the mutation? Thank you very much! Franc

Hi,I have problems with the MathCAD 15 on Windows 7 Enterprise. Attached is the error I’ve got when I scroll down.The user i'm using is Administrator and I’ve reinstalled MathCAD, SDK but no luck. What should I do?Aylmer.

When I try to run 3D plots with Windows 7 64 bit, it says "Failed to Launch Server Application."Has anyone else had this problem? Is PTC trying to fix the problem?Bill EdelsteinBaltimore, MD

I have Mathcad 15 and Windows 10 installed on my computer.  I am trying to use a Mathcad program which has some ComboBox's and/or drop-down lists embedded in it, and keep getting error messages (pasted below) about Microsoft VBScript runtime error...Object required: 'ComboBox'.  Any ideas how to fix this problem?     

Hello,In the attached example I cannot execute the formula described in the spreadsheet in Table 5.1.Maybe I'm the one who misplaced the formula or there's a printing error.Sincerely.Denis

Hello All,   I am having a bit of trouble with direct integration on the attached sheet. I have a data set provided in Excel format which I have converted to matrix/vector form and then to function form using cubic spline interpolation. Unfortunately I am having trouble integrating the resulting function in x and am receiving a "This calculation does not converge to a solution" error message.   I have tried changing TOL to ridiculous values like 1E-50, with no luck.   Any assistance would be greatly appreciated.   Many thanks and kind regards

Hi    Do we have the possibility  to have this contour colors showing utilization    

 

Hello, I'm attempting to use a For Loop to complete iterative calculations for multiple cases.  The program that I wrote works fine for single values (scalars), but doesn't work so well with vectors.  Results are coming out as scalar when it should be a vector.  I could use some help. Thanks

Hi everyone, I'm trying to solve a model that bundles different ODEs. However, it shows that I have too less equations although I have provided all the equations related in solving the ODEs. Please consult me if I've made mistakes in the equations. Thank you in advance.

I have an exercise in a class where I have to perform a Taylor expansion. I have read in the "help section" that the "series" keyword is able to perform this action. I have managed to do the expansion by hand an gotten the correct result, but as there is a keyword for being able to do this I would very much like some help figuring out how to do it, since it would be very help should it show up during the exam. I have tried to write it all kinds of different ways but with no result or the result being "0".I inserted an image of the exercise below.One of the things that really boggles my mind is that fact that there is an x1 and x2, and not knowing how to handle those as all the examples I have found only have 1 variable.    I really hope that someone is more experienced with this keyword than me, and is able to help.

Hi guys. I'm having some trouble solving for a variable mx (see attached worksheet). I think it's pretty straight forward and I'm just not seeing what i'm doing wrong..   I tried using a solve block, but didn't work, I'm probably just writing it up wrong.. I'm using mathcad 5 btw

Dear all,   I have a set of close points (every 20 mm for a 100m long curve) which I can import into Mathcad and use linterp to create a temporary function.    But when I need to call the function, I need the input to be the length of the curve. For example,   If I have a function y = sin(x) and I need to have a function which calculates the slope (tangent) at a distance 'd' but the distance is measured along the length of the curve sin(x) and not at x=d..   Is there any straightforward way of doing this ? I can think of one crude way (slowly start traversing the curve in small increments of x and keep on adding distance between y(x) and y(x+dx) until 'd' is reached and thereby now we know the (x,y) coordinates for the function and go from there). But I have to use this routine thousands of times and I don't think my method is efficient at all. Please suggest ?   Warm Regards, Aravind.    

I am still using MC 11.2   Sometimes I solve a set of math exercises, let say three of them, in the same MC document since they belong to the same exam. I was looking for a way to separate completely one exercise from the others, not only in terms of  layout (using "Insert Area"), but also in terms of variable definitions. In this way a variable defined in the first exercise would not be seen (and used) in the second and third exercise. This to avoid overlappings of data.   Is there a way to do this, like a command "clear variables", or isolation blocks,  that are in use in other math software? If not, is there a workaround to achieve the same result?   Thank you.

Hello everyone, I would like to create a Mathcad program that distinguishes whether the denominator of a given fraction is a polynomial or not, returning 0 or 1 for example. How do I do this? Thank you.

why can I not solve for this?

Hi all,We're starting to look at scriptable objects for Mathcad Prime 4.0. Mathcad 15 has two types of scriptable objects:Insert Component…- > Scriptable ObjectInsert Control -> Push Button, etc. (the so called scriptable controls a.k.a. Mathsoft controls)We'd like to understand better the use of each type. Specifically, one proposal is that we could provide an alternative scripting mechanism in the form of a function:The idea is fairly simple: execute an external script written in vb or jscript. The script could refer to inputs, x, y, z in this example, and could set outputs that in this example would be assigned to a, b and c.For example, expression above, where “my-script.vb” isSub PushBtnEvent_Start() Rem TODO: Add your code hereEnd SubSub PushBtnEvent_Exec(Inputs,Outputs) Rem first output is the sum of the arguments Outputs(0).value = Inputs(0).value + Inputs(1).value + Inputs(2).value Rem Second output is the product Outputs(1).value = Inputs(0).value * Inputs(1).value * In
