I bought single user license for Mathcad from Mathsoft Inc, over 20 years ago, When I bought a new PC about 10 years ago, I reinstalled Mathcad on my PC from a PTC CD. Recently I bought a new PC and tried to reinstall Mathcad but couldn’t  get a license to finish the install. The software returned an error indicating my laptop isn’t communicating with the PTC account. When I checked my account, I found out it’s a basic one and I don’t have permissions and need to upgrade it. In order to upgrade my account I need a Customer Number and a Sales Order. Since I purchased Mathcad from Mathsoft Inc, years ago I didn’t get any Sales Order nor did I get a receipt. I only got Mathcad floppy disks to install. When I got a new PC, I don’t recall exactly the process to install Mathcad however I have a PTC CD and installed Mathcad without problems. I don’t recall a need to get a Customer Number and any Sales Order.  Before I can reinstall Mathcad, I need someone in Account Services to get me a Custo

Scenario / QuestionThere is a built-in frequency unit "rpm" in PTC Mathcad Prime, which I assumed stands for revolutions per minute. But in Mathcad Prime 3.0 I find that 1 rpm evaluates to 6.283/min, or 0.105/sec, instead of 1/min, or 0.017/sec. I expected 60 rpm to equal 1/sec, that is 1 Hz, and that is not what Mathcad calculates. Am I missing something?OverviewThis is not a defect: in Mathcad Prime, rpm is an angular velocity, not an inverse-time frequency, and it is defined as 1 rpm = 2·pi/(60 sec) (0.105·rad/sec or 2·pi·rad/min). Because a radian is dimensionless, rpm still carries the dimension time to the power of minus one, so it looks like a frequency while differing from your intuitive "revolutions per minute" by the constant factor 2·pi. Mathcad Prime handles the same ambiguity for frequency by providing two units: Hz, defined as 1/sec, and Hza, the angular form, defined as 2·pi/sec (1·rev/sec).Step-by-StepOption 1: Use rpm as Mathcad intends, for angular velocity workTreat

Scenario / QuestionI'm working on problems where all the angles are in degrees, and I want the trigonometric functions to read them that way. Converting every angle to radians before each expression is evaluated is a lot of work. Can I add a statement or preference so that Mathcad evaluates trigonometric functions with degree arguments?OverviewNo. Mathcad has no setting that changes the default angle unit from radians, so trigonometric functions always treat a unitless argument as radians. Instead, attach the deg (or °) unit to each angle, or define your own trigonometric function that converts degrees for you. If you use the symbolic engine, you also need to define deg yourself, because symbolics do not recognise units.Step-by-StepOption 1: Attach the degree unit to each angleAdd the deg unit to the argument: Type the angle followed by deg or °, for example sin(90 deg). The result is 1. Show inverse results in degrees: Evaluate an inverse function such as asin(1), then type deg in the

Scenario / QuestionI am working in PTC Mathcad Prime and I need my results in kilograms rather than newtons, so I want Mathcad to treat 1 kilogram as 9.81 newtons. I also need to display pressure results in ksc (kg/cm²), but that unit does not appear in Mathcad's unit list. How do I convert between N and kg, and how do I add ksc to my worksheet?OverviewYou cannot convert newtons to kilograms in Mathcad, because mass and force are different physical dimensions and 1 kg does not equal 9.81 N. You can instead use kilogram-force (kgf), a force unit that is already built into Mathcad Prime, where the factor of roughly 9.81 is standard gravitational acceleration. The unit ksc, kilogram-force per square centimeter, is not predefined in Prime, so you must define it yourself as a user-defined unit and apply the unit label to it.Step-by-StepOption 1: Display a force result in kilogram-force instead of newtonsEvaluate the force expression: Enter your expression and add the evaluation operator so

Is there a way to do this.  Every thing I try has no effect.  I would like thicker error bars. 

Hi everyone, How to Create Summation from this Formula If you guys have any idea of thisPlease tell me how to solve this 

Hello,I need assistance with downloading and installing a compatible version of PTC Mathcad Prime.I am using Windows 10 Home, version 22H2 (OS Build 19045.6456).I registered for the official 30-day free trial of Mathcad Prime and received a download link from PTC. However, the installer provided Mathcad Prime 12.0.1.0.I attempted to install Mathcad Prime 12 twice, including running the installer as administrator. Both attempts failed with the following error:"The installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."I understand that Mathcad Prime 11 supports Windows 10 version 22H2, and I would prefer not to upgrade my operating system to Windows 11.Could you please help me with the following questions? Where can I officially download Mathcad Prime 11 for Windows 10? Is a free 30-day trial license available for Mathcad Prime 11? Can I use my existing trial registration to activate Mathcad Prime 11? Is t

I'm experiencing a login blocker on PTC (https://sts.ptc.com/adfs/ls/). Despite resetting my password, the portal continues to reject my credentials with an "incorrect username/password" error. Could you please verify if my account is locked or if there is a credential syncing issue? Thanks,

I am using PTC Mathcad Prime 12.0.0.0 (Academic). Whenever I change a result’s displayed unit, the calculation region turns grey and dependent expressions stop evaluating. Automatic calculation is enabled, but the AUTO indicator remains orange.Simple example: Define d := 3 mm Define a := d³ · π and evaluate it. Change the result unit from L to mm³. The result displays approximately 84.823 mm³, but the region stays grey and a subsequent evaluation of a shows “?”. Recalculating the worksheet does not resolve the issue.

Dear Sir or Madam, I am writing to request your assistance with renewing my Mathcad student license, as I need the software for my current studies. I have tried to renew my license through the usual process but have unfortunately been unsuccessful. I would therefore be grateful for your help in resolving this issue. Thank you very much in advance for your support. Kind regards, Holzinger C.

Hi, I have an active Mathcad Prime 11 Student Edition subscription. After a hardware replacement on my PC, my product code no longer activates, and the License Management portal shows no products on my account. Please reset my license so I can activate it on my current computer. Thank you, Noah McGuire 

Hi everyone,We use Mathcad Prime at work, and our license is managed through our own company server. My employer gave me the IP address and port details to enter into the settings for activation. However, I can't seem to find where to download the actual installation package.Our IT support told me to get it from the Mathcad website, but I can't find it there, and I don't have an official PTC account to log in. Any advice on what to do?

Scenario / QuestionHow do I use a plus/minus (±) operator in Mathcad Prime, and does Mathcad Prime include a built-in ± operator? OverviewMathcad Prime does not include a built-in ± plus/minus operator that can be used as an infix operator in expressions. A workaround is to define your own function that returns the positive and negative variations of a value, but it must be used as a function with parentheses rather than as a true ± operator. Step-by-StepDetermine whether you need a display symbol or an operator: A ± character can be displayed using supported Windows fonts, but this does not provide mathematical operator functionality. Create a custom function: Define a function that represents the plus/minus behavior you need. Use the function in prefix form: Call the function using standard Mathcad Prime function syntax with parentheses around the argument. Evaluate the result: The function can provide equivalent plus/minus behavior, but it cannot be used as an infix ± operator withi

I would like to request a temporary evaluation license for Mathcad 15 to perform local compatibility testing of a software integration demo. I already have the Mathcad 15 installation package, but I do not have a Mathcad 15 license. I have completed testing with Mathcad Prime; however, its trial license cannot activate Mathcad 15. I now need to separately verify compatibility with Mathcad 15, including opening and saving legacy worksheets, modifying input variables, recalculating worksheets, and retrieving results through its automation API. I understand that Mathcad 15 has been discontinued and that the previous trial licensing links are no longer available. Could you please confirm whether a short-term evaluation license can still be issued for this purpose? If not, please advise whether there is another authorized way to carry out this compatibility testing. The requested license would be used solely for local development and evaluation, not for production deployment. Thank you f
