## How to transform a function plot by "shifting" hor...

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,

Iza

## Background Images...

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 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

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

## Why Simplify is working only for output labels and...

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

## How do I solve for the real part of a variable?...

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

## How do I define a vector from its angle and length...

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

## simplify seems to have a bug here?...

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

## How to find a local extrema of a function?...

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.

## Why solution is wrong here?...

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?

Thank you very much!

## Need help with plotting a Tetrahedron using equati...

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!
