Mathcad

Using MathCAD 15 in Windows 7. Based on this quote from the help file regarding range variable creation:b is optional, but when used, it represents the value of a plus the step size to be used in generating the sequence of numbersI am puzzled by the values created by these two range statements:I understand the values for range variable i, but I thought j values would be 1, 11, 21. It appears as if MathCAD is calculating the step size as the difference between a and b versus using b as the step size. Am I confused or is the help file incorrect?

I have several problems with Prime 3.1:- Plots are not drawn for some parameter values. The same functions and parameters in Mathcad 15 work fine.- Number with ticks almost always overlap, making them unreadable.- I cannot use two Y-axes. This is needed to get appropriate scales and avoid very high and narrow plots.- I cannot add a caption to the Y-axis or move the legend to the left side of the graph. This means the graphs can never be used in publications.- I cannot turn off the units.Does anybody have a solution for these problems?Kind regards,Arjen Rinzema

HiHow do you calculate number of turn in a coilAn inductor core of reluctance 5.2 MA/Wb, cross-sectional area 245 mm2 and length 454 mm is evenly wound with a coil. When a current of 0.5 A flows in the coil, a magnetic flux density of 0.127 T is set up in the core. Calculate the number of turns in the coil.thanks

HelloIn the attached file I would like to retrieve the result of the "qu" equation for use in the following calculations.I don't know where to take it back or how?Kind regards.Denis

Hi,When sketching, I have trouble defining where a line measures from. Attached is a picture of what I mean (I'm having trouble explaining it). Right now the line is at a 160 degree angle but the length of the line is defined by the distance to the x-axis. Is it possible to change it so the line is defined by the angle and just length of the line? It's possible to just do the math and figure out the distance I need but that can take a long time. Any help would be appreciated! Thank you!

I am looking for a good book or on-line course in Signal Processing used mainly with real communication systems. Most seem to focus on the theory of the math, not the applications and techniques. Something that would be helpful to a practicing engineer wanting learn how they are used in real systems. I don't need to see every proof or get bogged down in nth-space theorems just some information on how devices in the digital world filter noise, error correct etc.

Dear valued Friends, please help me with this interaction diagram. it does not show the actual one....

Goodmorning everyone!Is there anyone  who can fix this little problem?Thanks a lot.F. M.

A train leaves New York at 9:45am EDT, heading for San Francisco...The train system consists of a straight-line tunnel connecting the two cities. The train uses a MAGLEV (magnetic levitation) system consisting of permanent magnets in the tracks and superconductive electromagnets in the train. To accelerate it uses a combination of electromagnetic force and gravitational pull of the Earth. The deceleration comes also from the gravitational pull of the Earth, as well as aerodynamic drag of the train.Problem: Compute the arrival time in San Francisco assuming constant propulsion force.

Hi guys, can anybody help me ? I have to create a Mathcad sheet to calculate the annual profit of a BOT (buono ordinario del tesoro or treasury bill in english). I am not expert with the software and any help will be appreciated ! many thanks,Tommi

Hello,I'm learning my way around Mathcad and I can find any examples of how to get multiple out puts from a program in Mathcad.For example, I need to get Vh,Vc and Vt1 as outputs for a graph from this program. Any suggestions?Thanks,Ken

Hello,I'm trying to get my first equation in Mathcad to work right.What we need to accomplish in this school project is fabrication of a (virtual) scale. More precisely writing a proper equation which would define the correlation between the weight of the letter/package placed on the scale, and the angle movement of the needle. It is hard to get it right algebraically when I'm not sure of how Mathcad reads the input.Can I request some help with the syntax of the equation?Thanks so much, maurits

Hi..I have created one design in mathcad which having some inputs from creo and one output from mathcad.So when i am going to do integration some times it gives me the error "Cannot read outputs from Prime worksheet" which i am not able to get the exact reason.Please can some one help me to understand, so i can take precaution while doing integration.Thanks,Prashant Pandarkar

where I get the product code ?

Hi, guys,As below shows, when I tried to perform a Duhamel Integral in Mathcad, If I manually copy and paste P1(tao) into D2(t), Mathcad will integrate successfully, as shown in the 2nd D2(t)However, when I used P1(tao) in the integral, the integration is not successful, as shown in the 1st D2(t), where the result expression has tao inside that is not supposed to be there. Could someone help me explain why?Thank you!BestShawn

Hi all,i want to write a program in MathCad 15, that can find a roots of the quadratic equation in subset of real numbers. Result will be a vector, or text: "this equation dont have result in real numbers" I already have a program, that can find a roots:but i dont know how to continue..i think, that if b^2-4*a*c <0 than this  equation dont have results in real numbers. but how can i write this in program?Thanks a lot!

Dear Valued friends,I got the error message when wrote the equation. please help

Hi All, I was creating a worksheet in calculating circuit parameters. I kept saving the file from time to time, but suddenly when I tried to save it again, some error messages showed, and asked me to either debug or close the program. This file now is showed 0 byte and cannot be opened. I attached it and would anyone help me about this? Thanks a million!
