## How can complex transformations be used to tile th...

Initial text in the uploaded worksheet describes an attempt to partially tile the Poincare disk and asks to be shown how a known complex transformation can be used to accomplish this.

## What hyperbolic transformation performs this works...

The worksheet below contains the desired hyperbolic action and asks for the specific transformation that performs it.

I have corrected the above worksheet so that the Poincare disk is now centred at [0,0].

I hope this helps you answer my question

## Signing in to Maple...

Every time I open Maple it has the invitation to Login in the top right-hand corner.  I would like to sign in but have had quite a bit of trouble doing that.  I have a user name and password with Maplesoft web store and the same for MaplePrimes.  Should either of these work to log in?

Hi. I can't seem to get my Explore plot to work. Maple gives me a cryptic error message (IMHO).

## How to find second solution of non-algebraic equat...

I want to solve the equation x^(1/x) =1.2
`solve(x^(1/x)=1.2)`

The output is 1.257734541376526421
How do i get the other solution, numerically.

Is it possible to restrict or stipulate the domain to look for roots over a specific interval, some rootfinding command over the real numbers.
I also tried `solve(x^(1/x)=1.2,AllSolutions,explicit)`
Wolfram immediately gives me the second solution. https://snipboard.io/Nqt74K.jpg https://snipboard.io/Nqt74K.jpg

Hi

I am trying to use Explore command to model the CSA  of a trough.

So I want to  be able to change the variables: length of the walls (l:, slider 0..20) and the width (w:slider 0..20) and the angle (theta: slider 0..Pi/2)

Want to be able to see the diagram change and also display the area using the formula [output (15)] on the graph

Here is my attempt.

How to change the distance (spacing) between 2D Input cells and 2D Output cells so that this procedure can be inserted into a style sheet and thus applied to multiple documents?

## Funny Maple Inverse Laplace Answers...

Run these codes

with(inttrans)

y := t -> invlaplace(exp(-s)/s, s, t)

y(t - 1)

y(t - 1.1)

and I cannot plot added shifted signals in time domain if their shifts are not integer numbers. Maple goes into infinite calculation loop.

## Remove an Error Message...

I want to know how to remove an error message from the last line of using Maple.  I must have made some kind of error, but I want to move on but I can't get past the error message.  How can I remove the error message.  I have tried using "restart" but nothing happened.  I'm stuck until I clear this error message from the last line of my worksheet.  Can you help please?

Thanks

Dave

PS: as you can guess I'm pretty new to Maple.

## Physics package problem with Define command...

Hello,

I have a problem regarding the physics package, which concerns, more specifically, the Define command.

It seems to be the case that it provides the wrong answer, and blatantly so, and I can't see what I am doing wrong for the life of me.

I want to build a fast way of doing coordinate transformations in general relativity, for which the basis vectors are called E[mu,~nu]. XX[~alpha] is the old coordinates expressed in terms of the new (in this case, the spherical coordinates are expressed in terms of cylindrical ones, i.e. [t,r, theta, phi]->[t, rho, phi,z].) As can be seen, only the first component in XX depends on time, but E contains weird elements (look at, for example, E[1,~2].) But when I do the calculation manually, it returns the expected results.

What am I doing wrong? I really appreciate any help you can provide.

## How can Maple display an accurate uniform tiling o...

This worksheet creates geodesics in the Poincare disk by transformation of a series of circles of diminishing radii in the complex plane.

The intersections of the geodesics are meant to create the first few pentagonal uniform tilings in the Poincare disk.

I do not know the mathematically correct way to create such a display, so the radii of the circles are only a trial and error approximation.

What Maple code will provide the radii of the complex circles which produce an accurate uniform pentagonal tiling?

Is there a better overall strategy for producing uniform tilings of the Poincare disk?
