I seem to keep running into things in Maple that I just can't get to plot. I have been using Mathcad and am trying to learn to do everything in Maple, but keep finding myself having to go to Mathcad to do even the simplest things. Could someone please help and explain to me what I'm doing wrong?
I have with(plots) and restart() at the top of my page.
I then do this:
g1 := implicitplot(3x^2,x=0..10,y=0..10);
display( g1 );
This results in it just printing the display line again, no graph is shown.
I can get this to work using the plot command but since its not very easy in Maple to print multiple equations on a single graph I have started trying to do them this way. If there is a better way to do graphs then please tell me this as well as I'm trying to learn Maple as best as I can.

I would like to plot a projection using parametric equations:
x=la*cos(fi)
y=fi
fi=

This is to inform you that we are now shipping the newest version of Maple T.A. – Maple T.A. 3.0.
Maple T.A. is an easy-to-use web-based system for creating tests and assignments, automatically assessing student responses and performance. It supports complex, free-form entry of mathematical equations and intelligent evaluation of responses, making it ideal for mathematics, science, or any course that requires mathematics.
The new edition – Maple T.A. 3.0 – comes with increased flexibility in content creation, an enhanced user interface and improved grading and assessment capabilities

How do I parse the response string with Maple TA? I can make my code work just fine in Maple but that is assuming what type of string $response is. If someone has dealt with this before, I would appreciate some ideas. I am asking for three parametric equations and need to seperate them and use all three for determining validity of the answer.

Hello, I am doing some research with solar panels right now and I need to try and come up with equations for a multiple input single output system. What I am doing is taking numbers from a website and comparing to the actual numbers from solar panels I have set up in a field. But the head of the project is wanting to make some unique equations. I can easily do a single input single output by curve fitting or splining the information, but I have never tried a multiple input single output system. Is there a way to do this?

I'm completely new to maple, and I'm trying to solve some equations that have no algebraic solution but should be straightforward to solve with numerical methods. I'd be most grateful if anyone could offer some advice on how to do this.
For example, I'd like to solve the following two equations for p:
2^(1-p)+(1-x)^(1-p)/(1-p)
and
x^(2-p)-y^(2-p))/(x-y) = (a^(2-p)-b^(2-p))/(a-b)
The attached worksheet contains my unsuccessful attempts.

I have a question which has three parametric equations as the answer. I then need to parse out variables from these equations and make sure the 3 equations satisfy 4 conditions. How do I have $response equal 3 different equations? My answer would be coming in as x=$a+$b*t, y=$c+$d*t, z=$f+$g*t.
I would then use the variables a-g in my tests.

Hi everyone!
(I'm Fench, hope my English isn't too bad).
I use Maple to solve non-linear differential equations using a numeric method, and I plot these solutions using the basic:
>slnew := dsolve({set1, set2, a1(0) = 0, a2(0) = 1, (D(a1))(0) = 0, (D(a2))(0) = 0}, {a1(t), a2(t)}, numeric);
>plot1 := odeplot(slnew, [t, a2(t)], t = 0 .. 10, numpoints = 10000);
So far it's ok. However, I'd like to compare the difference between the solutions when the initials conditions are slightly different, say, a2(0)=1.1 . So I use the same procedure to create a plot2, and I use:
>display(plot1,plot2);

I am running Maple 11 with a mac-intel MacBook (13'' screen). I have been running a procedure for plotting a system of differentail equations that depend on an arbitrary parameter. The procedure works well for some "simple" parameters. For some more complicated parameters, the memory count (bottom right hand size) goes from near zero to over 500 M in six seconds ! A message appears: "kernel connection lost", and warns that such problems could be due to firewall settings, but all my firewall software is off.
This procesure on these parameters works just fine with Maple 10 running in a PowerBook G4 (firewall connection also off).

Dear Comrades,
I'm trying to solve a system of coupled integral equations. Does anybody know how to use IntSolve? And what's the shared library? Do I have to download IntSolve from somewhere? And is this the best way to spolve integral equations if I did?
Regards,
Andrew

I have a system of equations where unkowns are functions of variables
` > eqns:= {a(s,y,z,t)+2*b(s,y,z,t)=0,3*a(s,y,z,t)-5*b(s,y,z,t)=0}; `

I would like to get the matrix associated to the system.
I tested genmatrix but maple returns `equations are not linear `
Anyone have an idea of how to do this?

I am having this common problem when solving trig equations. I read "?solve" but missed something somewhere because I still don't know how to solve this problem. Taking a simple example of solve(sin(x)=1,x) the answer returned is Pi/2 and while Pi/2 is a correct answer, because of the periodic nature of the sin function there are others. So maple for some reason (which doesn't make sense to me at all)is limiting the range/domain and therefore not providing the complete answer which is Pi/2 +2nPi where n is any integer. I tried to force Maple to consider a larger range by using assume(0<>

Hi,
First of all, I'm quite new to Maple and here, so I hope you will be patient with me..ehhehe.
I've been struggling some days creating abstract vectorial equations with no luck.
The equations have vectorial components as well as a matrix, it is the equation of motion, i.e:
Inertia * dw/dt + w x Inertia.w = T
Inertia is a matrix that I dont want to define now, and most of all I dont want to spread out its components, so it has to be all the time "Inertia".
w is a angular speed vector and T is the Torque vector.
Neither I want w to be defined or component separated (wx,wy,wz) at this point since I need to work with w for some change of coordinates .i.e w = w1 + ww1 . So I need to work in this abstract level.

Has Maple 11 changed the way you do mathematics?
For me, it has.
For me, Maple used to be a “mechanized mathematical assistant”. That is, when I was doing something mathematical, I would do it at my desk, with Maple on a computer beside me, to assist with some of the calculations. I used many sheets of paper; the papers were messy and disorganized. I would scribble equations, scratch out mistakes or recopy the good parts onto another sheet, have sub-results strewn about haphazardly, etc.
With Maple 11, things are different. Now I do mathematics almost entirely within Maple. Now I keep everything in a document. I type formulae with 2D input, which looks much like how I would write things on paper, except neater. Graphics are interwoven with the formulae (and can be scribbled on). Mistakes are erased within the document. Sub-results are nicely put into collapsible subsections. The organization can, and of course does, change as I figure things out.
