MaplePrimes Questions

I am trying to solve a differential equations with the periodic coefficients, which have the following form:



In the attached workbook I define a function that contains an if. This seems to confuse the plot function when I try to plot my function. How do I plot this function?




Is it possible to a plot,  shown in worksheet, insert vertical lines using the Builder plot ?




What is a pulse height analyzer?
What math behind the PHA? DFT FFT?


Hello everyone

Yes, im just another one with problems during loadingproces. 
Just lost my assignment in advanced engineering mathematics, and I do not know what to do.

Anyone who can help a friend in need?  


The file is attached. 


Thanks in advance

Hey there in the file above, i have an equation with units, that maple dont seem to be able to solve.


Its the equation at the bottom on the box.


Can anyone tell me what i am doing wrong?

I have a piecewise function which I require to be transformed to a fourier series.

The function to be transformed is:

         velocity:=piecewise(t<=6, 3*sin(t*Pi/6), t>6, 0);

How can I change this to a fourier series in a simple manner.


Thanks for your advice.

Is there a way to make the x, y and z axes thicker in 3d plots?

I want to do a Monte Carlo study with the following probability distribution:

P(X=x):=(x-1)*q^(x-2)*(p^2+(2*(1-p-q))*p)+binomial(x-1, x-3)*q^(x-3)*((1-p-q)^3+(1-p-q)^2*p);

with x = 2. 3, ... infinity and parameters p and q with 0 < p+q < 1. For the Monte Carlo study I ave to generate samples with specified values of p and q. For this I have yo do something similar to:

use Statistics in T:=[1/2,0,0,0,0,0,1/2];


Hello Everyone,

I am using Maple for printing out my calculations which already look good. I wonder if there is there a way to draw a box around some important resutls or equations, something like the "\boxed" command in LaTeX?




I would like some help with this. As so many others  i get this meassage "There were problems during the loading process. Your worksheet may be incomplete." when i treid to open my, almost done, Math assignment.

so i looked the problem op and found that i could retrive alot of my work by changing some lines of code. I could not find the problem.


Any help?



ps. I realy realy realy hope you guys can help me!

By setting zeta_t:=`&zeta;&tilde;`: %; I can get ζ˜ as output.
However I don't find it satisfactory. I would like to have the tilde above the ζ without shift.

Thank you in advance for your suggestions.

I cannot make a worksheet function as it should in MapleNet 11. It contains a graph and a slider to adjust the graph. It looks fine, but when I try to read the value of the slider I get an error message "Error: ecslider17 not found". The worksheet works perfectly in "offline Maple".


Any suggestions how to fix this will be most welcome.

I have been running up against a memory limitation when running v15 from a Linux Ubuntu workstation.  The memory indicator in Maple gets up to 39.36M but will not go above that.  After I reach this limit I am still able to perform further computations but Maple gets slow and eventually crashes.  Here is one of the lines from the error message:

Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC overhead limit exceeded

I have been using the DirectSearch package contributed by Dr. Sergey N. Moiseev.  It works very well for the problems I have been working on and would like to use it in Matlab.  Is anyone aware of a Matlab version, how I may convert this to a Matlab file, or call Maple from Malab?
