Hi, I have a problem with one element array in VBScript component. VB decide that it`s  TypeName is Double and VarType is 5 instead of Variant 8204 and CStr() gives "-1.#QNAN". So, I can`t get a value of my array. MC15 file is attached.

I need to find the X value for the following function where it breaks. Of course I can do it manually, but I would like to have a function, say Cr(D,u1,u2) that would give to me the x value where M(D,Gama,u1,u2) breaks.Can Anybody tell me how to do it? or Simply giving to me any function that does it?       Thanks in advance

Hello, Could anyone help me with fitting a Gaussian curve to the signals, please? In the attached worksheet, the function "plane1(k,x1,y1,d,taw)" detects the ultrasonic pressure filed amplitude on two microphones placed on the right and left side of the emitter. The peak of each signal is used to estimate the time of flight (TOF). For more accurate estimation of TOF, I use genfit to fit a Gaussian curve to the signals. However, the output of the fitting process (result(Data,taw)) does not look right and it sensitively depends on the scanned time range. In the current example, the signals time range do not exceed more than 0.01 s but the Gaussian fit works only when the time range is scanned up to 0.2 s. Is there something wrong?   Any suggestion would be highly appreciated, Payman

Hey, I am trying to model the second order differential equations for the shock absorber. I would like to get the funtion of the movement of the mass. I am getting errors from the Solve Block in MathCAD, and I cannot understand where is it coming from. I suppose the reason is the sin function x(t), but I have no idea how can I write it differently. Without units the solver was working fine, but with units I get always an error. I am uploading the MathCAD file. I would be glad for some hints and tipps! Any help is welcome!   Best regards, Jolanta

Hi,   I want to know that is there any way to unlock protected area if someone forgot password for locked area.   Thanks, Prashant Pandarkar

Hello, I'm Mathcad newbie and I am unable to solve the attached problem in mathcad.  how to plot voltage vs df/dt and voltage vs f

Hello Everybody, I have problem with Lim and differential equation. 1. How to get Lim (variant t) for function p(t): as attachment picture? 2. Can we get symbolic formula for function p(t)?   Thank in advance!

Hi,   I have one csv file which will get modify  by another application. and i want to link this csv with mathcad and use their values for further calculation.   I checked but first time it got imported but if csv got modified the values from mathcad sheet not getting modify so please can some one suggest how can i achieve this.     Thanks, Prashant Pandarkar

When doing symbolic math, sometimes the result has exponents of exponents, for instance   (x^2)^(3/2)   A simpler form for this expression would be x^3, but even using "simplify,max" does not change the form of the  result. "combine" and "expand" don't help either.   Is there any way to get Matchcad to simplify this expression?  

Hello Everybody, I have a query with interpolation: We have 2 tables of data X1 and X3 with 4 items for each table (or matrix, vector)X1 at value of arguments 10 X3 at value of arguments 20 I want to interpolate at 12 of arguments? Can anyone help me?  

Hello, I'm Mathcad newbie. I am unable to solve to get the results of figure 2, in mathcad. can solve ...... thanking you.

"Browsing", among the questions asked to the community of PTC Mathcad, I see that there are some of the year 2000 .... but I also see that my recent publications (a few years ago) on analog equivalent-digital filters (Electrical Engineering), are unavailable .......why?

There is: Lemniscate of Bernoulli Lemniscate of Booth Lemniscate of Gerono Victory Lemniscate (now is 8-9 May) - see the animation bellow Questions: Do you know one more Lemniscates? Can you create more intelligent method as in attach?      

Hi All,   I have written an iterative formula on pg 10 of the attached but cannot work out why it doesn't work. Could someone please give it a second look? Thank you in advance for your time and help.   Cheers, Dan

Hello. I have the following function:   There are two intervals above 0 in which the value of the function is bigger than 0.2. How can I get those intervals?   Thanks!

Hello, I'm Mathcad newbie and I can't get it to do anything useful... Given the following set of equations: I provide values for f and Cs: Now I'd like to 1/ Provide Rp value and get Rs value OR 2/ Provide Rs value and get Rp value.   How can it be done without duplicating the equations ?  

... I see that, from a bit of time, .... old stuff goes back to the surface ... ..... while the Mathcad community gives me the impression that, is sinking ...... in the hands of a madman ....

Say I have an equation of:  Cc = 78.4232/(acosh(1+5.05/Cc)+acosh(1+12.85/Cc)   I know how to calculate this through a calculator but not through any means of mathcad tricks. Please help! I'm new to mathcad. (P.S. I've went to many forums and when people also ask about these kind of questions the answers are ALWAYS telling them to simplify the equation by hand (not through mathcad) and then use mathcad to solve. e.g. x = sqrt(12.85/5.05)*(78.4232-x)^2
