Hello,

I will explain my problem on a simple function and some data.

mg:=78.54*7.85*1e-9*1000*9.81;l:=10000;l0:=12000;h:=0;H := 28.399;
eta:=mg*l/(2*H);
zeta:=arcsinh(mg*h/(2*H*sinh(eta)))-eta;
z:=H/mg*(cosh(mg/H*x+zeta)-cosh(zeta));
plot(z,x=0..l);

Above is a definition of an initial plot. Now I would like to draw a new plot in which every x coordinate is shifted horizontally by a function:

deltax:=H*arcsinh(x)-x;

As you see I can't use translate or scale so I've tried to use a transform function but I can't do it the right way.

I would be grateful for any ideas.

 

Greetings,

Hei!

In my Maple project I want to put a simple sin graph on top of an image. But how do I create a background image with a graph on top?

I'm start making an homepage about mathematic and wondt to link a workpage writen in Maple 16 into WP, thanks to whose ho have any idea :)

 

I am getting this error for pretty much everything now, i am using maple 16, and there literally is no way i will be able to buy a newer version considering

PDE := diff(u(x, y), x, x)+diff(u(x, y), y, y)-6*x*y*(1-y)-2*x^3 = 0; BCsx := u(xL, y) = 0, u(xU, y) = y*(1-y); BCsy := u(x, yL) = 0, u(x, yU) = 0; solPDE := pdsolve({BCsx, BCsy, PDE}, u(x, y)); exactSol := unapply(rhs(%), x, y)

I am getting this error for almost everything that i write in maple today, and i simply have no idea what causes it or what it means

Hi, i will post the executed code so you can see what i am saying, essentially i want to know what i am doing wrong here to have simplify not work as a command line function but  it does when i right click the output and select it and the equation label of that output is inserted as the oprand.

I feel like maple is not wanting to be entirely forthcoming with me today or something, but in a more deeper contemplation, i see that refering to the maple interface as if it is a sentient entity is a true indication that i need a social life.

 

But as you will see, the same failure occurs for the ListTools partial sums feature when implemented in commandline code, but works perfectly well when it is selected by right clicking on the output intended

Hi

I am trying to solve an inequality for the real parts of the solution to be less than 0. How do I do that? When trying to use solve, and specifying Re() Maple warns about lost solutions. I can see there are complex solutions to the equation, but i cannot make Maple calculate them. Maple gives me a range for the real solutions (6.1.11) and (6.1.12), but if I use a number out of the range the inequality is still met, the solutions is just complex, which does not matter. The variable a seems to be able to be between -8 and 3 for the real part of the solution to be less than 0.

Kind regards

Simon

hey guys does anybody know if i can define a vector from its degree and lenght. instead of having to use coordinates?

the only way i know of defining a vector so far is

Vector1:=<x,y>

sorry my english is'nt the best

I'm just unable to see how this could be correct, if someone can take a look it would be much appreciated.

So I've got a function and try to find an extrema (and there is one on the plot), but Maple gives me empty brackets.

First, earlier it gave me 2 x-coordinates with extrema (both empty), but now (after reloading) it gives one and empty.

Second, how do I set an interval, if I want to look for extrema from x=0 to x=1, for example? I tried extrema (V, {0,1}, x) and (V, {x=0, x=1}, x), but nothing seems to work.

 I am trying to solve 2 equations in maple:

 1/  solve({1<x or x<3 or x>5});

 {x=x}    solution is correct

 2/  solve({1<x or x<3 or x<5});

 {x<5}    solution is wrong

 How do I have solution correct is {x=x} in Maple?

 Please teach me about this.

 Thank you very much!

I think that I am probably making this more complicated than it needs to be, but I'm fairly certain that the way that I am doing this is possible within Maple. 

 

Currently I have this line of code

>implicitplot3d({2*sqrt(2)*x-2*z+sqrt(2) = 0, 2*sqrt(2)*x+2*z-sqrt(2) = 0, 2*sqrt(2)*y-2*z-sqrt(2) = 0, 2*sqrt(2)*y+2*z+sqrt(2) = 0}, x = -2 .. 2, y = -2 .. 2, z = -2 .. 2)

 

So these equations create planes that intersect creating a tetrahedron. The problem I'm running into is that I need to "trim" the extra bits of the planes outside of the tetrahedron. The idea I have right now is constraining each plane by 3 equations which would turn the planes into triangles. I think this will work but I'm not sure how to constrain each individual plane with different equations AND plot them on the same graph. Any direction here would be greatly appreciated. I would prefer to stick with using implicitplot3d and avoid any special plotting tools. 

 

Thanks for any help!

hello everyone!!

I need to plot the function x^3-x^2-x-1, and in the plot I need to calculate de point X that make the function equals to cero (the cutting point with the x axis).

Thanks you!!
