Olá a todos,

Gostaria de pedir ajuda a quem dispuser de um tempinho na seguinte questão:

1- Estou tentando reproduzir um código da tese de doutorado do professor Sérgio Dantas (*), para produzir a figura abaixo e não consegui.

2- O Código que estou utilizando é este: Sequência[homotetia[girar[q1,i*arctan(1/7),E],((5*sqrt(2)/8)^i,E)],i,1,n].

3- Ocorre erro, pois o Geogebra pede o número "E" e "E" é um ponto, o ponto Central do quadrado inicial.

4- Haveria uma maneira mais simples para realizar isto ?

5- Segue o arquivo em anexo.

Hi, you mean :

`Sequência[homotetia[girar[q1,i*arctan(1/7),E],(5*sqrt(2)/8)^i,E],i,1,n]?`

you can use iterations with something like that :

`l2 = IterationList(Enlarge(Rotate(truc, atand(1 / 7), E), 5sqrt(2) / 8, E), truc, {q1}, n)`

Hello Michel,

Thank you very much for the directions. Thank you.

I applied them but they did not work. I believe that problem is with the point "E", which gives an error. I could not solve it.

Regarding the command you sent me, Geogebra gives the error below:

Hi Math,

Thanks for the usual help!

In Portuguese: ListaDeIteração(Homotetia(Girar(truc, arctgg(1 / 7), E), 5sqrt(2) / 8, E), truc, {q1}, n)

Dear Michel,

Thank you so much for your precious help.

It worked great! Thank you very much!

When I converted to Portuguese, the term "Truc " remained as "Truc ". In the Geogebra command site, this command does not appear. What does it do?

Thank you so much for your help!

Marcelo.

"truc" is used 2 times, it's only the name of a dummy variable and not a command. You can change the two "truc" to "ronaldo" if you want

Ok, I understood.

Thank you!
