"Maplesoft is committed to providing the highest
level of support for the products it sells"

...............................................................

Dear Maple customer, please eat yet another
Maple regression bug, one of many 1000s.

Bon appetite!

...............................................................

DESCRIPTION: Only Maple V Rel 4 of 1995 and Maple V Rel 5
of 1997 can calculate this limit correctly.

TEST CASE: limit(1/sqrt(1+z^(z^z)), z= -1);

EXPECTED: undefined

CHECKUP: limit(1/sqrt(1+z^(z^z)), z= -1.001);
limit(1/sqrt(1+z^(z^z)), z= -0.999);

9.335771067 + 1.323435694*I
1.312891021 - 9.280839335*I

-------------------- (2005) Maple 10.00 ---------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2004) Maple 9.5.1 ---------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2004) Maple 9.5 -----------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2003) Maple 9 -------------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2002) Maple 8 -------------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2001) Maple 7 -------------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (2000) Maple 6 -------------------------
limit(1/(1+z^(z^z))^(1/2),z = -1)
-------------------- (1997) Maple V Rel 5 -------------------
undefined
-------------------- (1995) Maple V Rel 4 -------------------

-------------------- (1994) Maple V Rel 3 -------------------

 Quote: DESCRIPTION: The solution to a boundary value problem for an ODE of the second order depends on a free parameter _C2. Only Maple 6 of 2000 can solve this BVP correctly. TEST CASE: dsolve({diff(y(z),z\$2)= y(z)/z^3, y(0)= 0, y(1)= 1}, y(z));

The DE has an irregular singular point at z=0, so specifying a boundary
condition at z=0 is a bad idea in general. dsolve is not sophisticated
enough to handle something like this.

 Quote: EXPECTED: y(z) = 1/BesselY(1,-2*I)*z^(1/2)* BesselY(1,-2*I/z^(1/2))

This does not go to 0 as z -> 0+. The real part
goes to +infinity and the imaginary part to -infinity.
Try this:

 Quote: y(z) = limit(rhs(dsolve({de,y(p)=0,y(1)=1})),p=0,right);

y(z) = (BesselI(1,2/z^(1/2))+BesselY(1,-2*I/z^(1/2)))/
(BesselI(1,2)+BesselY(1,-2*I))*z^(1/2)

 Quote: Buy Maple, The World's Most Screwed Computer Algebra System

As someone who lurks around here sometimes could you explain to me what
your interest in Maple is? If you feel its the worlds most screwed
computer algebra system why don't use just ignore it

Or perhaps use my CAS below which is bug free - always computing the
result exactly with no bugs. (Assuming your compiler or operating system
are not broken of course).

Here is the source code - feel free to copy and redistribute if you wish.

#include <stdio.h>
int main(int argc, char **argv)
{
printf("1 + 1 = 2\n");
return(0);
}

I just downloaded a scientific calculator for my Pocket PC and found it
was very poor indeed. But I don't feel the need to make a life-long
hobby out of pointing out how bad it is to others. I just delete it and
move on.

You mean this?

product(sin(k/1), k=1..1);

1
sin(1)

limit(product(sin(k/n), k=1..n), n = 1)

would not be too bad, as I already pointed out. But in fact,
in the given case, I do not feel it's really material what

The main point is that Maple 8 - Maple 9 - Maple 10 return
a piece of total bunk, exp(sum(ln(sin(k)),k = 1 .. n)) .

M> You shoult "limit" yourself to the real Maple bugs,

Take it or leave it, but right away I am the # 1 world's
QA engineer in this field.

This said, please realize that the showed publicly stuff
is a far cry from my last word in the field.

M> You shoult "limit" yourself to the real Maple bugs,

Jocularly speaking, with the course of time, I decided that
I was too lazy to discover Maple bugs.

This is why I invented the VM machine we keep implementing.

But of course, this explanation shows only one of the
aspects of why I decided to do it; now it's still ahead
of time to discuss this.

M> or have you discovered all of them?

The VM machine has already discovered far many more
distinct Maple bugs than we the human being have done
and posted to public domain, altogether.

However, the shower of distinct Maple bug manifestations
is not getting weaker...

One fine day, not tomorrow, we will come back to this
point.

 Quote: ................................................................ DESCRIPTION: The value of the limit depends on the point where the limit is taken. TEST CASE: limit(product(sin(k/n), k=1..n), n = 1); EXPECTED: sin(1) # best limit(product(sin(k/n),k=1..n),n=1) # tolerable

Your expected value is not correct, because the side limits for n --> 1
are not equal:
limit to the right = sin(1)
limit to the left = 1.
You shoult "limit" yourself to the real Maple bugs,
or have you discovered all of them?
