Default Yet another Maple bug the long liver, 1992--2007--? (integral, Error, (in X) numeric exception: division by zero)


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

Hello again from the VM machine...

.................................................. ................
BUG # ***XX int (1-D): Error, (in X) ... division by zero

REGRESSION: NO

REPRODUCIBLE: ALWAYS

BUG HISTORY:

PRESENT Maple 11.00,IBM INTEL NT, Feb 16 2007 Build ID 277223
PRESENT Maple 10.06,IBM INTEL NT, Oct 2 2006 Build ID 255401
BUG* Maple 9.51, IBM INTEL NT, Aug 9 2004 Build ID 163356
BUG* Maple 9.50, IBM INTEL NT, Apr 7 2004 Build ID 155251
BUG* Maple 9.03, IBM INTEL NT, Oct 1 2003 Build ID 141050
BUG* Maple 9.01, IBM INTEL NT, Jul 9 2003 Build ID 137227
BUG* Maple 8.00, IBM INTEL NT, May 10 2002 Build ID 111221
BUG* Maple 7.00, IBM INTEL NT, May 28 2001 Build ID 96223
BUG* Maple 6.01, IBM INTEL NT, Jun 9 2000 Build ID 79514
BUG* Maple V, Release 5, IBM INTEL NT, Nov 27 1997
UNEVAL Maple V, Release 4, IBM INTEL NT, Dec 15, 1995
UNEVAL Maple V, Release 3, IBM INTEL NT, Jan 10, 1994
UNEVAL Maple V, Release 2, IBM INTEL NT, Jan 10, 1992

DESCRIPTION: During 15+ years Maple cannot calculate this
integral.

TEST CASE: int(sqrt(cosh(z)), z= 0..infinity);

ACTUAL: Error, (in EllipticPi) numeric exception:
division by zero

EXPECTED: infinity

CHECKUP: evalf(Int(sqrt(cosh(z)), z= 0..24));

230168.8352

COMMENT: BUG* = 2^(1/2)*EllipticPi(1,1/2*2^(1/2))

UNEVAL = int(cosh(z)^(1/2),z = 0 .. infinity)
