In the media today, there continues to be much discussion about how students in North America are moving away from the math, science, and engineering disciplines. It is an established fact that countries such as China, South Korea, and Taiwan graduate a much higher number of engineering students than those in North America. This is a cause for great concern in today’s highly complex world, and schools are attempting to solve the problem with math in a variety of ways, with varying success rates.

Hi,

 

I am kind of new with using maple, and I am hoping that someone can give me some help on nonlinear curve fitting.  I checked out the help topics, and I thought that I had put everything in correctly, as per the help file.  However when I try to do a fit to data, nothing is returned.  Here is what I have input:

 

Hi all, I'm not good at maple, so need a help from experts. I'm using Maple v.12. -part of the code- ... de2:= # Nonlinear DE is here # ics:= X(0) = 1, (D(X))(0) = 1; sol:= dsolve({de2, ics}, numeric, method = rkf45); (or sol := dsolve({de2, ics}, x(t), numeric, stiff = true, range = 0 .. 200);) Error, (in f) unable to store '1.0000000024691*{1.}^2+2000010000.' when datatype=float[8] -end of the code- As you see above, It's a simple process to solve DE. so most of the DE, like (1) below, is solved very well through the code. But my case is (2). I could see error msg as you see above.

Good day, I cannot run this maple, why?

I need help!

I'm trying to plot a sphere, and then shade-in the bottom one-third of it.  Is that possible?

Also, I then need to plot a sphere with 8 approximating disks.

Does anyone have any ideas of how to do these?

I have a Matrix O[n,m]:=Value with n:=1..10 and m:=1..10 How can I present the values in a 3D plot with x->n Y->m and Z->Value. One time I want to make a histogramm out of it and in a second case just connect them to a surface How can I do that Thank you very much in advance!

Hi,

have a look at this plot, i'm using standard worksheet (in classic this problem doesn't exist). 

plot(sin(x),x=-5..5,tickmarks=[default,20]);

Instead of -for example- 0,5 i want decimal points 0.5

Playing with the tickmarks option would do the trick, but a "global switch" would be better.

What to do ?

Hello everybody, I was wondering, is there a way to call procedures from a different worksheet? I am writing a big procedure which calls many smaller ones and that would be really clearer if I keep them in a different worksheet.. Thanks a lot in advance..

Hi, I have a polynomial expression like this:

2*a^32*b^3 + 3*c^2*a^3 + 4*a^5*c^2

I would like to apply rules like these ones:

a = a^x and b = b^y,  ∀ x,y ∈ N*

It should result:

2*a*b + 7*c^2*a

I would do this manually, but I intend to use this to really big expressions and it would be quite boring. Any ideas?

 

Thanks in advance and sorry the english,

Dear experts, I want to plot a matrix with B[n,m] and n:=1..10 and m:=1..10 The problem is that the plots achses are labled with n and m. I want to lable the achses with N:=0.25 to 2.5 in steps of 2.5.... How can I do that?

Hello everybody, I am a bit stuck here because I have the problem above, any help would be really appreciated.. E1:={{0,2},{0,7},{0,a},{0,b},{1,3},{1,8},{1,9},{1,a},{1,e},{2,3},{2,a},{2,d},{2,e},{3,4},{3,6},{4,8},{5,7},{5,a}, {5,e},{6,c},{6,e},{7,8},{7,a},{7,e},{8,b},{9,a},{a,c},{c,d},{c,e},{e,f}}; for e in E1 do e; end do; {0, 2} {0, 7} {0, a} {0, b} {1, 3}

Hello everybody, I have a question, any help would be really appreciated. Let me illustrate my problem with a small example. Say I want to define 1000 variables like this: x_1:=1; x_2:=2; x_3:=3; .... x_1000:=1000; That would be very tedious to be done by habd so I would like to use a 'for' to do that.. Is that possible? The code below does not work: for i from 1 to 1000 do x_i := i ; end do; Any ideas? Thanks a lot in advance..

Hi all!

So I have an equation like so:

I have to plot a graph of the resistance against variable frequency of up to 1Ghz.

So I am plotting for frequencies 1Hz, 1x10^2, ... 1x10^9

Question is, how do I use Maple to input a set of frequencies into f of the above equation, giving out the resistance, and then plot a graph.

I am new to maple.

Thanks in advanced.

Regards,

daniel
