Does anyone know of the bugs that still exist in ROM E? In particular
is the sin/cos bug fixed yet?
ie: what does the following result in?
'(A,<B)' {enter} * where < is the angles character
if it is the following then there is still a bug in ROM E:
'B*cos(A)+B*sin(A)*i'
it should return the following:
'A*cos(B)+A*sin(B)*i'
Thanks.
Sincerely,
Jason P. Meyers

I just tried it out on a Rev. E machine, serial number 3041A00894, that I got last week from EduCALC. My Rev. A machine has it, of course. Speaking of new versions, the manuals are dated 7/90; I guess they must have fixed some typos there as well. The carrying case they are shipping now has a zipper; mine has a velcroed flap. The tiny rubber feet in the Rev. E have little dimples, for better traction I guess. /ji In-Real-Life: John "Heldenprogrammer" Ioannidis E-Mail-To: ji@cs.columbia.edu V-Mail-To: +1 212 854 8120 P-Mail-To: 450 Computer Science \n Columbia University \n New York, NY 10027
