Hello

I have question. How can I rotate this 2-D plot and create 3-D plot?

plot(exp(-(x-3)^2*cos(4*(x-3))),x=1..5)

Thank you.

hi my friend. i want to find a approximately function of this plot. how i can get this. and i have numerical value in this excel

Dear community, 

I'm new to maple and was wondering if you could help me out.

I have this curve where I want to make a line that goes from x=0.5 up to its value on the curve in this case 1.60 and then all the way to the y-axis so there is an area under the curve which I can color if that's even possible?

I have the following in maple:

k := 2.5;
                              2.5
Ca0 := 1;
                               1
v := 20;
                               20
Ca := Ca0*(1-x);
                             1 - x
Fa0 := Ca0*v;
                               20
Cb := Ca0*x;
                               x
ra := k*Ca*Cb;
                         2.5 (1 - x) x
plot(1/ra, x = 0 .. 1);
 

thank you for your help

Best Regards

Saad

I can not understand why the following statement works perfectly:
with (plots);
P1: = plot (f (x), x = xmin .. xmax, y = ymin .. ymax, color = "green");
P2: = plot (orddir, x = xmin .. xmax, y = ymin .. ymax, color = "blue");

Plots [display] (plottools [line] ([ascf, ymin], [ascf, 10]), color = red;
Plot ([5, y, y = 0 .. 10]);
P3: = implicit plot (x = ascf, x = xmin .. xmax, y = ymin .. ymax, color = red, linestyle = 3, thickness = 2);
P4: = plot (points, x = xmin .. xmax, y = ymin .. ymax, style = point, symbol = circle, symbolsize = 20, color = "black");
P5: = plot (h, x = xmin .. xmax, y = ymin .. ymax, color = "yellow");
Display ({p1, p2, p3, p4, p5}, axes = normal, scaling = unconstrained, title = "Parallel, vertice, focus, direction and axis of symmetry", gridlines = true);

While in the following
Points: = [F, V, A, B];
with (plots):
P1: = plot (f (x), x = xmin .. xmax, y = ymin .. ymax, color = "green");
P2: = plot (yd, x = xmin .. xmax, y = ymin .. ymax, color = "blue");
P3: = implicitplot (x = xv, x = xmin .. xmax, y = ymin .. ymax, color = red, linestyle = 3, thickness = 2);
P4: = plot (points, x = xmin .. xmax, y = ymin .. ymax, style = point, symbol = circle, symbolsize = 20, color = "black");

Do (% Plot0 = display ({p1, p2, p3, p4}, axes = normal, scaling = unconstrained, title = "Parallel, vertices, focus, direction and axis of symmetry", gridlines = true));

P4 does not print anything. In thanking you for the kind attention, I cordially greet you. Carmine Marotta ..

Hi everyone,

as a very basis example I've tried to get the equipotential lines of an 1/r² potential in the x-y-plane using contourplot. However, I obtained the following very strange result. Do you get the same mistake or is there something wrong on my end?

Thanks in advance,
Sören


 

with(plots):

plots:-contourplot(1/(x^2+y^2), x = -2 .. 2, y = -2 .. 2)

 

plots:-contourplot(1/(x^2+y^2), x = -2 .. 2, y = -2 .. 2, contours = 5, numpoints = 100)

 

plots:-contourplot(1/(x^2+y^2), x = -2 .. 2, y = -2 .. 2, contours = 5, numpoints = 1000)

 

plots:-contourplot(1/(x^2+y^2), x = -2 .. 2, y = -2 .. 2, contours = 5, numpoints = 10000)

Hello guys,

I´ve a little bit problem by plotting an pyramid with an triangle in it. When I want to display both

parts, in the drawing the left and the right part and the top of the pyramid is missing. What is the problem ???

hi
i want to draw a plot with to column-numerical that i imported from excel (i import one of the, for x axis and another for y axis)

All the 3d plot in my maple are upside down.....the tickmarks..the numbering even the lebeling are also upside down...how do i solve it....plz help

I have a complex function for both the electric and magnetic fields for 2 laser pluses colliding they are only 2 dimensions z,t;

E(z,t) := -I*a*exp(-(z-Z+t)^2/sigma^2)*sin(omega*(z-Z+t))+a*exp(-(z+Z-t)^2/sigma^2)*sin(omega*(z+Z-t))

B(z,t) := -a*exp(-(z-Z+t)^2/sigma^2)*sin(omega*(z-Z+t))+I*a*exp(-(z+Z-t)^2/sigma^2)*sin(omega*(z+Z-t))

Where a,omegasigma are real constants and Z is the initial offset for the pluses,

I would like to plot them together with there real and imaginary parts on two axes and then extended along the z direction, if possible I would like to animate them. To hopefully get a moving plot like this except it's a laser pluse not a continuous wave,

Hi!

If somebody could help me it would be awesome!

I would like to be able to switch the independent variable onto the vertical axis!

If that is not possible, what i'm trying to do is modelise in a function a set of points, but with multiple values for the same x, but not more than one for the y, so the best option would be to switch the variables, to have x dependant of y. My graphic has to be vertical though, so I can't just switch the points.

Thank you a lot

I am plotting a pair of lists of points using

pointplot(Listap, Listbp, symbol = point, symbolsize = 1, size = [1200, 1200])

 

How could is do this with plot so I can add colours? Along the lines Listap(i)^2+Listbp(i)^2 =R, R is in the range 0..1,then colour =R*256 or any other imaginative way of adding colour.

Hello, I am trying to plot an expression for my General Relativity class, this expression is one of the expanding universe FLRW solutions to the Einstein field equations and contains an unknown functions.

sqrt(S(t))*sqrt(1+S(t))-arcsinh(sqrt(S(t))) = t

My question is how do I get maple to plot this?

Thank you

Hi guys,

I've had only a little experience with Maple, but I decided to use it for preliminary frequecy response calculations. The funny thing is, I have already the solution in some way, but I'm too stupid to get it working. I can't see the mistake, however, it should have something to do with the H_n(f) function and the other normalized functions.

NASA has published a nice paper which explains the calculations, however, they have used MathCAD. Anyway, I don't think this should be a problem. Here is the documentation: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20070016024.pdf 

The error message is for example for the H_n(f) function:

Warning, expecting only range variable f in expression H__n(f) to be plotted but found name H__n

 

Please help me.

I have made an animate-plot with trace function enabled and I was wondering if there was something I could do so it would show the value of the variable when trace reached frame x and y and plot it in the plot or maybe somewhere else.

Thanks in advance.

Hello,

i have a Problem with maple. I have written this simple procedure

myPi_1:=proc(r)
local i,l;
l:=0;
for i from 1 to floor(r) do
    if isprime(i) and (i mod 4 = 1) then
        l:=l+1;
    end if;
end do;
return l;
end proc:    

 

When i use it like this 

k := myPi_1(80);

it works

But when i triy to plot it

plot(myPi_1(t), t = 0 .. 500, numpoints = 500, thickness = 2, color = black);

i get this message
Warning, expecting only range variable t in expression myPi_1(t) to be plotted but found name myPi_1

And no plot

Thank you for any Help
