Dear Maximers,
I have recently noticed that my maxima on clisp2.27 failed to complete
rtest3.mac. Problem 93 is OK. However problem 94 failed due to the
different answer.
Is a well-known issue? How can I fix maxima so that this test returns OK?
My environment is:
clisp 2.27, maxima-pre59 with for59 build, Mac OS X10.1
Yasuaki Honda,
Japan
/* ********************** Problem 93. *************** */
%Input is
2 2 2 2
SECH (X) TANH(X) COSH (X) SECH (X) TANH(X) SECH (X) SINH(X) TANH(X)
---------------- + ------------------------- + ------------------------
2 2 2
COTH (X) COTH (X) COTH (X)
The result is
2 2 2 2
SECH (X) SINH(X) TANH(X) COSH (X) SECH (X) TANH(X) SECH (X) TANH(X)
------------------------ + ------------------------- + ----------------
2 2 2
COTH (X) COTH (X) COTH (X)
..Which was correct
/* ********************** Problem 94. *************** */
%Input is
TRIGSIMP(%)
The result is
4 2 3
SINH (X) + (COSH (X) + 1) SINH (X)
----------------------------------
5
COSH (X)
Using ratsimp
Using ratsimp
This differed from the expected result:
3 4 5
2 SINH (X) + SINH (X) + SINH (X)
--------------------------------
5
COSH (X)
The number of differences found was 1 in problems: (94)
