I want to set the position of the legend inside the figure window for example say top right in the figure window. Maple chose the legend to be at right, left, top, bottom outside the figure window. How can I place the legend of my own wish?

thanks,

Hi, everybody.

I have a problem when I try to plot3d a sub-surface from a surface as follows:


 

S := proc (u, v) options operator, arrow; Matrix([[40*u], [80*v], [10*u^2*v+20*u*v+15]]) end proc;

proc (u, v) options operator, arrow; Matrix([[40*u], [80*v], [10*u^2*v+20*u*v+15]]) end proc

(1)

S(u, v)

Matrix(3, 1, {(1, 1) = 40*u, (2, 1) = 80*v, (3, 1) = 10*u^2*v+20*u*v+15})

(2)

 

p:= proc(u,v) if u<v then S(u,v) else S(u,v)+10 end if end proc:

h:= proc(u) 2*u  end proc:

plot3d(p, 0 .. 1, 0 .. h)

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

Please help me!

 

Thanks and have a nice day.

 

 

I have final project to make a media for learning mathematic using maple. But I'm so confused to make a net of cuboid, anybody can help me? please :D

Dear All,

Please, could anyone point me out how to draw the beautiful Apollonian Gasket using Maple?

Thank you.

Very kind wishes,

New color schemes for plotting have been added to Maple 2016. They are summarized here. You can also see more details on the plot/colorscheme help pages, which have been reworked (hopefully in a way that makes them more useful to you).

We released a new video a few weeks ago describing one of these features: coloring by value. The worksheet I used for the video is available here: ColorByValueWebinar.mw

 

We have a new video about plotting with procedures, specifically on how to avoid an error related to evaluation that many people make. 

The worksheet I used in the video is available here:  PlottingWithProcedures.mw

By the way, this mistake doesn't occur just in the context of plotting. Users of Optimization commands (and other commands that allow functions to be expressed as either an expression in a variable or as a procedure) frequently run into this problem too.

 

Hello everybody,

 

my question concerns the visualizing possibilities of maple:

can maple visualize complex functions? (f(z): C->C)

If so, which possibilities do i have und what is the command for it? Maybe as a coulour diagram, as a vector field (f(x): R^2->R^2) , or as mapping of sets (e.g. curves, grids into new curves and curved lines)?

 

 

 

Thanks in advance

regards

Nikita

 

PS: I am using maple 18.

Hi,

I have a problem with maple solving diffusion equation. I solved the equation as follows

Es := 0.117108e12;
Ef := 0.78125e11;
l := 0.150e-6;
s := 0.500000e-3;
f := 0.5898334197e-6;
o := 0.9e-5;
d := 0.10e-17;
cb := 0.1e7/(19.9);
c := l*f/(d*cb);
PDE := diff(u(x, t), t)-(diff(u(x, t), x, x)) = 0;
IBC1 := {u(x, 0) = 0, (D[1](u))(0, t) = 0, (D[1](u))(1, t) = c};
S1 := pdsolve(PDE, IBC1, numeric, time = t);
S1:-plot(t = 0.6e-2);

i am plotting cincentration along the thickness of the material. i want to know why the concentration is negative. It should not be negative because constant flux 'c' is present at x=1. and flux at x=0 is 0, and also the initial concentration is 0.

Thanks

 


Hi,

I'm pretty new into MAPLE andI'm trying to get into it.

I have these four equations:


eq1:=1.6*10^(-7)*R*sin(t)-4.4*10^(-14)*R^2*cos(t)*sin(t)-1.6*10^(-14)*R^2*cos(t)^2+4.2*10^(-14)*R^2-1.3+2.1*10^(-9)*R*cos(t)=0; eq2 :=8.3*10^(-8)*R*sin(t)-1.2*10^(-13)*R^2*cos(t)*sin(t)-2.9*10^(-44)*R^2*cos(t)^2+7.1*10^(-14)*R^2-1.3+8.3*10^(-8)*R*cos(t)=0; eq3 :=8.3*10^(-8)*R*sin(t)-1.2*10^(-13)*R^2*cos(t)*sin(t)-2.2*10^(-44)*R^2*cos(t)^2+7.1*10^(-14)*R^2-1.3+8.3*10^(-8)*R*cos(t)=0; eq4 :=2.1*10^(-9)*R*sin(t)-4.4*10^(-14)*R^2*cos(t)*sin(t)+1.6*10^(-14)*R^2*cos(t)^2+2.6*10^(-14)*R^2-1.3+1.6*10^(-7)*R*cos(t)=0;
 

Hi, Very new to Maple. This is a math assignment, and well I am not exactly sure what is happening. I have had a buddy to help me, but things are not necessarily working. Using Maple17.
This is what I have so far.

de := sin(x)*(diff(y(x), x))+cos(x)*y(x) = Q;
/ d \
sin(x) |--- y(x)| + cos(x) y(x) = Q
\ dx /
dsolve(de);
Q x + _C1
y(x) = ---------
sin(x)
ab := 75; Q := 2-0.1e-1*ab; M := 4+0.1e-1*ab;
75
1.25
4.75
PS := simplify(dsolve({de, y((1/2)*Pi) = M}, y(x)));
-10 x - 38 + 5 Pi
y(x) = - -----------------
8 sin(x)
z := rhs(PS);
-10 x - 38 + 5 Pi
- -----------------
8 sin(x)
N := evalf(subs(x = .4, z));
8.439521805
a := z, x = 0 .. Pi, y = 0 .. 10; b := plots[pointplot]([(1/2)*Pi, M]); c := plots[pointplot]([.4, N]); d := plots[pointplot]([x0, y0]); plots[display]({a, b, c, d});
z, x = 0 .. Pi, y = 0 .. 10
