## Limit...

Hi Markiyan Hirnyk

I thought it was obvious that we were at infinity ... Ok, I forgot to write down the little "x" !

Anyhow I see you are a smart guy and you saw quickly what was wrong !!!

Best wishes

## program : question...

Hi Carl Love,

No, so far I do not have any question

Best wishes

## thanks...

## straightforward question...

Hi Rouben Rostamian,

I just want to know the procedure to copy paste an entire worksheet to mapleprimes !

I hope it's clear enough...

## Gershrin's circles...

Anyhow, the centers of the circles are all lying on the Real x-axis.

Y=Im z, x= Re z.

Here are the equations of the circles:

1. (x-3)^2 + y^2 =25/36
2. (x-4)^2 +y^2 =1
3. (x-5)^2 +y^2 =1
4. (x-6)^2 +y^2 =1                                                                                                                                                            I tried to plot them, without success...

## sets and relations...

hi,

Indeed it's shorter !

hello,

nice job !

## linear algebra...

hi,

many thanks about that quick and nice response !

## conjecture a new way to get a solution...

Very nice way congratulations !!

## the exclusion-inclusion principle...

Hello, I tried a formula, based on the number of surjections :

> sum((-1)^j*binomial(3, j)*2^j*factorial(2*3-j), j = 0 .. 3);
240
Manys thanks for your replies !

## paraboloid...

I see you are right !!

How did you find the y extent ?

Regards
