MaplePrimes Questions

 

Dear my friends

Hi

I have a linear partial differential equation to solve.

> equ1:=F5*(diff(phi[2](r, theta), r, r)+(diff(phi[2](r, theta), r))/r+(diff(phi[2](r, theta), theta, theta))/r^2)+F3*phi[4](r,theta) = 0;

where F5 and F3 is constant and phi[2](r,theta) is unknown function.

I tried to solve this equation by the following Maple's command:

> pdsolve(equ1,phi[2](r,theta));

When I type

cos(x), sin(x)

and start the Plot Builder (using the contextual menu) the first option it gives me is for a 2-D plot.  However, when I type

cos(x), x

and start the Plot Builder the first option is a 2-D polar plot and the "standard" 2-D plot is nowhere on the list.  Is this a known bug?  (I'm using Maple 15.01 on Windows 7.)

 

Thanks,

We have the following sequence of natural numbers 1, 4, 9, 13, 11, 27, 25, 37,.. . What is the next term?
Is it possible to find it with Maple? The approach
> with(gfun):
>l:=[1, 4, 9, 13, 11, 27]:
>rec:=listtorec(l,u(n));
fails because it produces a noninteger value of u(n) for some natural values of n.

 

Hello all,

I'm familiar with using _ and ^ to enter subscripts and superscripts in document mode. However, the only way I know of moving out of those modes is to use the arrow keys. I was wondering if there was an alternative shortcut that wouldn't require me to move my hands from the home row?

Thanks,

Amr

EDIT: I have figured it out (somewhat), so nevermind!

I wrote this in my AddSystem:


However for output that should be unitless, I still get units (which can be cancelled), like this:

hi

 

i want to export figures in maple to word. in other software like Tecplot when we use WMF format, the figures saves like a vector and when magnifiyng picture , quality remains good. but in maple when i export figure as WindowsMetaFile the quality of figure decrase and decrases with magnifing. i want to know how i export figures in maple to keep quality high. thancks

In my Maple program results are exported to a file. But the problem is that I should write a path every time manually that complicates a work. Moreover, I often forget to change a path and correspondingly new results would often rewrite previous results stored in other directory. The reason is that the path of stored results folder have to be the same as the path of Maple code run.

How can to do it automatically? How to make that Maple knows a path from where Maple...

Hello. I'm studying engenieering mathematics at DTU and I just started working with Maple. When I tried to open my work in progress I got the following message: "
There were problems during the loading process. Your worksheet may be incomplete".

Some of my colleges are experiencing the same problem...

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 ?

GRACIAS

 

 

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

Gracias

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.
