Just a comment.
If in another case you experience problems with plots actually being inaccurate (offcourse all plots are in some degree inaccurate, especially 3d plots).
The argument "numpoints=integer" can be used.
example:
with(plots):
> plot3d(cos(3*x)+sin(y), x = -10000..10000, y=-10000..10000, axes=normal);
> plot3d(cos(3*x)+sin(y), x = -10000..10000, y=-10000..10000, numpoints=2000, axes=normal);

Hi.
I only see an red x, where the double integral should be.
But here is an example of an double integral in maple:
int(int(x*y,x=0..a),y=0..b);

Hi Doug.
Just to learn.
As far as i can tell, the only difference, is that the assigne command returns NULL, are there any other advantages?
//Sentinox

Method 1:
> vec1:=[var1,var2,var3];
> vec2:=[a + b_+ c,exp1,exp2];
> var1:=vec2[1];
> vec1;
Method 2:
>vec1:=[var1,var2,var3];
> vec2:=[a + b_+ c,exp1,exp2];
> vec[1]:=vec2[1];
> vec1;
Hope this was what you had in mind?

Hi.
I suppose you mean fractions?
There are several ways.
An approximation can be done via "evalf"
example:
evalf(2/10);
Alternative you van use the "convert" command:
example:
convert(2/10, float);
convert can also be used the other way like this:
convert(0.2, fraction);
Hope this was what you needed.

Hi.
Just download 10.06 update.

Hi.
I am not quite sure if I completly understand what you mean, but please try this example, and se if this is what you need:
Maple code start:
> restart:with(plots):
> f:=x^2+y^2+t^2:#Function to be animated
> g:=30*x+y:#Plane
> p1:=animate(plot3d,[f,x=-10..10,y=-10..10],t=0..10):
> p2:=plot3d(g,x=-10..10,y=-10..10):
> display(p1,p2);
Maple code end
As far as I remember, this can also be done eith the "background" option, please see animate help if needed.

Hello Again.
Just to specify.
The package name is:
Maple2e
and should be availble on most reposetories.
In case you can not find it, please send me a PM.
//Sentinox

Hi.
You can export an entire worksheet to latex sourcecode by "export -> latex" in the file menu.
To compile you need to have the file : "maple2e.sty", in the source directory.
//Sentinox

Hi.
Try to use:
> with(student):
> completesquare(x^2-2*x*c+c^2+y^2 = 1,[x,y]);
> completesquare(x^2+d+y^2+c^2+1/2*k-2*x*c = 1,x);
//Sentinox

Either you define the function f as a Maple function:
f:=x->a*x^2-b*x-c;
g:=f(x1)-f(x);
(alternatively yo can also define the function g as a Maple function using "unaply")
Or via subs or eval, exaple with subs:
f:=a*x^2-b*x-c;
g:=subs(x=x1,f) - f;
Please notice that the constant, c, will dispear, since it does not depend of x.

Hi Brandon.
Could you please upload the maplesheet, with the exact problem?
//Sentinox

Hi.
Engineering + Scientific I do not remember, and can not find in the help file...
Fraction:
>convert(12345.678, fraction);
Decimal:
You can use the evalf[6](12345.678);
Please notice the rounding!

Hi.
Maple can be used with units for example with the units package:
Initialisation:
>restart:
with(Units[Standard]):
Units[UseSystem](SI):
Know maple knows that you wish to calculate with SI units, but you still need to inform Maple every time you calculate with units.
Your example(requires the above Initilisation):
>F = 5*Unit(kg)*1*Unit(m/s^2);
Please notice that the output will be in Newton [N].
//Sentinox

Hi. You can also use this approach: remove(has,allvalues(solve([eqn],[var])),I): where eqn are yor equation(s) and var are the variables you solve for. Please notice that this requires that the global variable: >interface(imaginaryunit=I): has not been changed. //Sentinox
