Arrrghh.... this calculator is really annoying me.
I've put my fx-991MS calculator into CMPLX mode, and I can get it to
"calculate" and show me, for example, the real and imaginary parts of 1 -
3i
(simple I know but it definitely works). However I can't get it to show me
the real and imaginary parts of, for example, 1 - sqrt3i. It says "Math
ERROR". This also happens with *any* other complex numbers calculation
involving roots or powers.
Am I missing something fundamental about this particular type of complex
number?
There's almost no point in the complex numbers functionality implemented
in
this calulator if it can only work with simple complex numbers. Could
someone with the same or similar Casio calculator tell me if the same
happens on theirs? I specifically chose this calculator because it was the
most expensive of it's type in the shop so I'm gonna be annoyed if this
doesn't work.
If I could get this to work it would help me a lot - normally I would be
fine about calculating by hand - but I've got a multiple choice exam next
week and having the calculator there and fully functioning would be a big
help.
Any suggestions?
