Re: [fricas-devel] Deriving the Poisson distribution, can I symbolically compute this limit?

> I don't want to be to hard on FriCAS since I know this involves 2 variables. It's not about 2 variables. p := product((n-i)/n, i=1..(x-1)) limit(p, n=%plusInfinity) That is equvalent to p1 := product(1-i*n, i=1..(x-1)) -- eval(p, n = 1/n) limit(p1, n=0) FriCAS can handle

Re: [fricas-devel] Deriving the Poisson distribution, can I symbolically compute this limit?

It should be solvable: p1 := eval(p, n = 1/n) limit(p1, n = 0) The result is "1^(x-1)" I think this is a bug. There should be something added for 'exprToGenUPS', like r1645 for 'exprToUPS'. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer

Re: [fricas-devel] Deriving the Poisson distribution, can I symbolically compute this limit?

Thanks for looking. I don't want to be to hard on FriCAS since I know this involves 2 variables. I know I can do better than numeric eval: If I eval(p, x=30) :: FRAC POLY INT and then take the limit it works, and I can map across many x's to check. But it if course would be nice to check every

Re: [fricas-devel] Deriving the Poisson distribution, can I symbolically compute this limit?

FYI, here was the code I was thinking about in my last reply. map(j +-> limit(eval(p, x=j) :: FRAC(POLY(INT)), n = %plusInfinity), [-5, 0, 1, 15, 20, 23, 30, 50, 100]) On Mon, 8 Jan 2018 at 08:07 Kyle Andrews wrote: > Thanks for looking. I don't want to be to hard on

[fricas-devel] exterior algebra dual's?

I apologize if this is the wrong forum for posting coding requests. Perhaps Sandbox instead? I have had this in mind for years but never had a practical example. One has a set of simultaneous equations that one wants to investigate. The two logical possibilities are Groebner analysis and
