...not to be forgotten. It comes from the Irish MO of 1990, Paper 2, Problem 9, and, as a student-friendly problem, is one of the most difficult I've ever encountered:Let t be a real number, and let (a with index n) a_n = 2*cos(t/(2^n)), n=1, 2, ...Let b_n be the product a_1*a_2*...*a_n. Simplify the term b_n so that it does not contain a product of n factors, and prove lim(n-->00) b_n = (2*cos(t)+1)/3 .

I have a loop with two conditions in it, none of which are satisfied.I created a variable 'a' and defined it as zero, and inside the loop, I made it change 'a' to 1 if the If conditions are satisfied. as shown in the figure below, a is still zero after the loop, meaning the conditions are not satisfied. However, the vector y4 is modified even though it only has equations to modify it inside the same conditions for variable 'a', which is unchanged:what am I missing here?I attached the file. Using Mathcad Prime 9.0.00thanks

I am using Creo Parametric Release 11.0 and Datecode11.0.3.0The Preview File button has disappeared from the File Open window. I use this feature all the time. Please advise how to restore the function. I have searched the config options but no luck. Thanks.

Translator             Hi,I am facing below error. I am reading a .txt file with some data points, and I want to make/have a function like f(x) interpolating teste data points. Prime 10 file attached.

The Measurement Tool... (Analysis->Measure)... was changed was back around Creo 2.0 or 3.0 to a "new, improved" GUI. Back then I complained loudly to the PLM for modeling tools and he was annoyed that I thought the new tool was inferior to the old one.    In any decently sized assembly, I find the tool to be nearly useless. Tips like "pre-selecting the first reference" help but the should software function in a reasonable time span nonetheless. PTC says it "works to specifications" but taking 4 minutes to measure between two holes cannot possibly be "intended functionality".   What are your thoughts? Any tips for improvement? Or do we all just avoid measurements now?  

Hi allI'm at the start of the free trial period.  i have the converter installed and have tried to convert files.  The converter acts like the files are converted and sent to the source folder but the conversion does not take place.  I cant access other support so hope you can help - thanks

Bonjour, Je rencontre un probleme lors de la conversion de ce fichier, La matrice T existe bel et bien mais mathcad dis le contraire

  Hi,How to take the discrete fourier transform of this signal and plot the magnitude vs frequency and phase vs frequency by using Mathcad Prime dft built in function? Suppose that we will sample this signal at 4 time per second (fs=4Hz) from t=0 to t=3/4. I have tried something manually, but how to show phase plot I do not know right now...   Prime 10 file attached.

Hello, I have a Mathcad sheet which I am working on to find the factor of safety for block walls. The sheet will calculate and spit out a text "Stable", "Unstable" based on a comparison , which I have provided in the logic. What I request to have is a Mathcad prompt, that checks the array FS_OT to see how many "UNstable" are there. If so, it should send out a message saying "UnStable" and tell me at which level of the layer of blocks are unstable. Please help on this as I am not that pro level. My Mathcad version is Prime 10. This is not an error issue so no screenshots were provided. Thank you very much 

  Hi, I am sure that something I do not do correctly, I believe there with that condition of an=0.       Prime 10 file attached.

I've got a part with two dims that I've renamed from their original symbolic names (example: d123) to C and D.  How do I find their original dimension names if I've forgotten what they were?

When rendering images with the Render Studio package that comes with Creo 10. Bump maps, which I use all of the time to represent things like fiber wrapping on tanks, iso grid structure, weld beads, etc., are not being scaled per my inputs.  This is especially useful for representing threads. I have a basic raster image for threads that I apply to a threaded surface, and just scale it along the revolve axis as needed to represent the number of threads that should be there as a function of the cylinder length, and the thread pitch.  Thread bump maps are being rendered, but with a default scale of 1 along the rotational axis. These results are whether I use a parametric or cylindrical mapping for those textures. I don’t know if there is a setting I missed, a configuration value I overlooked, or what.

Hello, is there a method to know the file size in Mb of an assembly or part in creo or in windchill? Tank you, Michele Barile

Hello, I'm having a hard time understanding units in Mathcad. I'm trying to plot an axial capacity vs depth after integrating the Axial_cap function with different depth. It works without when i have no units, but it shows an error : "These units are not compatible". I don't understand what's the problem.

I am trying to add onto a part which opened up from an assembly. I make the thing I was trying to make but the save buttons are all greyed out. Not sure how to fix this any help would be appreciated. The model also had a validation import failure, but I just clicked ignore. Idk if that's the cause but it still won't let me save. Thanks! 

I am working on generating a imperial drawing for a part that was designed using metric standards and the Model properties use mm as the base unit. The drawing is using dual dimensioning SECONDARY to allow me to dimension in inches. However the part also has several threaded holes that have hole notes generated. This means that the hole and thread depth are using the mm from the model when bringing it into the drawing (so instead of 1in depth the note looks to appear as if it had 25.4in depth). Is there a way to make the hole note that gets pulled in to use the secondary dimensions of inches that the drawing is using so that it matches the units of the drawing without setting the model properties to inches and updating the note in the model.

Is it possible to block the System colors, Interface and Theme options in Creo Parametric (10.0.6) from unauthorized user changes through config.sup?

Dear Creo users,While doing some complicated sketch don't you think there is a need of linear and circular pattern options in creo sketch? Its true pattern option is given in solid modelling and we can pattern a feature or group of features. In solid works users can pattern inside sketch mode. in creo 3.0 and 4.0 is there any updates on sketch pattern? I am using creo 2.0.With regards,Soumya

1.どのような製品とバージョンを実行していますか?Creo Parametric 8.0.1.0 2.問題はありますか?アーティクル - CS364641にて、CreoParametric5.0以降でモデルチェックレポートのカテゴリが変更になったとあります。現在、新しいUIでのカテゴリの定義ができませんが、できるようになってほしいです。3. 回避策を使用していますか? 「はい」の場合は、それについて説明してください。config.proに「modelcheck_show_new_report_ui no」を設定すると、古いUIでのカテゴリの定義ができることは確認しましたが、新しいUIでのカテゴリ定義はできません。 4. あなたの組織のユースケースは何ですか?モデルチェックのカテゴリは、チェック内容を的確に探すために、大変有意義な機能です。複数のチェック項目を追加した場合、よりそう思います。 5. この問題は現在、あなたの組織にどのような影響を与えていますか?Creoのバージョンアップ時に機能が損なわれました。 本機能の改修についてご検討のほど、よろしくお願いいたします。

Hey folks!Need a bit of help...So I’ve got this huge assembly in Creo that takes forever to open — like 30-40 mins easily. When I peeked into the task manager, I noticed it’s only using a single CPU core, even though the machines/workstations have quad-core and some even octa-core processors. Is this normal for Creo? Or is there some any setting or config tweak I may be missing that can make it use all cores and speed things up?Many thanks in advance.Ciao,Srikar

Hi,I am adding a decal to my part, and as suggested in this ticket, I used the flip decal buttons to correctly align my image. Solved: Invert/Mirror Decal Appearence - PTC Community However, when I go to render my part, the image is "unflipped". When I get out of the render application and back to the modeler, the decal is in the correct orientation.  Any thoughts on what can be happening here?  Example decal on the part, as seen in the model view Same decal in the render view  Thanks!

Hello,I am using Mathcad Prime Release 11.0 and Datecode11.0.0.0Regarding the page number format, is there a way to start page numbering with a number other than "1"?If not, is it possible to manually insert the page numbers into the header of each page?
