Re: HP50g DESOLVE Help Message #4 Posted by Chuck on 24 Apr 2007, 11:49 p.m., in response to message #2 by Happy HP User
Hmmm. No go. So here's a simpler one that I tried...
['d1d1y(T)+y(T)=0' 'y(0)=2' 'd1y(0)=0']
'y(T)'
DESOLVE returns (after a simplification)
(e^(iT))^2 + 1
y(T)=---------------
e^(iT)
It would be nice if it just gave back 2cos(T). :(
The obvious modes shown on the screen are:
RAD XYZ BIN C='T'
In the CAS MODES I have Complex checked, and Simp Non-Rational checked.
The system flags that are checked are {27, 34, 40, 56, 57, 68, 76, 82, 90, 103, 117, 119}
My version number is #2.09
Any more clues????
Thanks.
