@Kitonum Your answer is not correct. I prefer arguments over "So what?"  etc.

PS. I'd like to quote again "However, how can we know that desired 95% outcome can be determined from the first 5 terms without trial & error?".

PPS. Unfortunately,

``` lambda := 2.6:
solve(sum(lambda^k*exp(-lambda)/factorial(k), k = 0 .. n) >= .95, [n]);
Warning, solutions may have been lost

```

## Are you serious?...

```lambda := 2.6: add(lambda^k*exp(-lambda)/factorial(k), k = 0 .. 4.980237188);
0.8774234889
```

Pay attention to the difference between sum and add. What you do is

```lambda := 2.6:sum(lambda^k*exp(-lambda)/factorial(k), k = 0 .. n);
(1.000000000*(2.600000000^(n+1.)*5.^n*GAMMA(n+1.)-2.600000000*13.^n*(GAMMA(n+1.)-
1.*GAMMA(n+1., 2.600000000))))/(2.600000000^(n+1.)*5.^n*GAMMA(n+1.))
fsolve(% = .95);
4.980237188
```

This is not it as it was noticed by me in my previous comment.

pirates books. I deleted it.

## So-called...

@Teep The pleasure is all mine.

## Could you kindly explain...

PS. I'd like to quote "that desired 95% outcome can be determined from the first 5 terms".

## Recent articles by O. V. Kaptsov...

I'd like to present an article by O V.. Kaptsov " Local algebraic analysis of differential systems" and his article "Algebraic and geometric structures of analytic partial differential equations"  where  Groebner basis is exploited.  BTW, the author refers to the PhD thesis of Allan Wittkopf and Maple.

## Have you looked in the help...

@Kitonum

•  numframes = posint
 The number of frames for an animation. The default value is 50.

to this end? Good luck!

## There is an animate =true option...

@Kitonum in the Explore command.

## Does not work...

@Rouben Rostamian  for mu1=mu2.

## "Physical Review D" 87, 044053 (2013)...

expresses much without words.

## Clarification...

The posted procedure is not any proof of any case. Since fsolve is not an exact solver, the SQ procedure  produces a quadrilateral  which is approximately inscribed in a given parametric curve. No more and no less.

## Incorrect references...

@Christopher2222 You wrote

• Google is quick to fix it's errors.

Unbased as well as

• Mathematica releasing more updates per version might just mean they have a lot more problems to fix.

here. If you were a solid person, you gave a reference to the long path.

## The question arises:...

is Maple a CAS or a Google substitute?
