## How to adjust width and height of animat...

Maple 2018

Hello

When i export an animation as a gif the dimensions are (by default it seems) 400x400 pixels (w x h).

But my slide show requires a dimension of 1920 x 1080 pixels.

How to I tell maple to export a gif of predefined dimensions?

I can manually adjust the dimensions of the animation by grabbing a corner and pulling it right and down and then export it, but its hit and miss.

Here is an example animation written by Kitonum

restart;
with(DEtools):
rho := 0.1:
w0 := 2:
sys := a->[diff(x(t),t) = y(t),diff(y(t),t) = -2*rho*y(t) - w0^2*(x(t)+a)];
P:=a->DEplot(sys(a), [x(t),y(t)], t = 0 .. 20-2*a, x=-2..2, y=-1.9..1.7, [[x(0) = cos(a)-a, y(0) = sin(a)]], scene = [x(t),y(t)], linecolor=blue, numpoints=1000):
plots:-animate(plots:-display,['P'(a), size=[600,300]], a=-0.7..1.4, frames=90);

## Encrypt Procedure Question...

Maple 2018

Hello

I found this example in the Help.

I'm wanting to export the encrypted file (the gibberish between local and end proc) to friend running another M2018, and want it to run.

I would need to rerieve "abc.mla" repository that we saved it in. But I cant find it. and if i did send it, he would be able to decrypt it surely?

## Survivor probability question...

Maple 2018

On CBS tv show Survivor S38E4, an interesting scenario arose. There was initially 2 teams comprising 6 persons (blue team) and 9 persons (yellow team). Then they decided to mix it up, and split it into 3 teams. Each player was randomly assigned a buff, (red, green or orange =3 colored buffs *5).= 3 teams of 5.

What was interesting was 5 out of the original 6 blue team are now in the new red team. 5 of the original yellow team are in the new green team and 4 of the original yellow team are in the new orange team.

What is the chances of that happening?
A couple of attempts:

## Currency convention...

Maple 2018

Hi

I would like to designate AU as currency for my application, rather than the USD.

I can do it to a degree, but when I use combine I have problems. Compare output 8 and 9 to 17 and 18. help?

## Predict Perfect...

Maple 2018

Hi

Initially I tried to find pemutations of 1..9, ie [[1,2,3],[4,5,6],[7,8,9]],[[1,2,4],[3,5,6],[7,8,9]],...etc, But maybe not all of them?

I wonder if someone out there can change my code to reflect the following:

1/According to the pdf excerpt, there are a total of 199 unique sums, the smallest sum is 774 and the largest 2556.(From displaying 280 outcomes, the code got the 774).

2/Show which sums have the greatest probability (specifically, 1566, 1575, 1638, 1656, 1674, 1692, 1755, and 1764, each of which can be shown with effort to have a 3/280, or 1.07%, probability – the calculations to determine this probability is a brute-force computation, and requires enumerating all outcomes of the sample space within a computational software package). We then finally reveal the prediction, which of course is correct..(I don't get it)
