In addition to joining the line ->Y1 on to the end of the preceding
line, as suggested by another responder, I think you may want to correct
the argument of sin( to B*X + C . The possibility of two-letter
variable names on the TI-86 (and other higher-end TI models) is a
common headache to the person switching back and forth between this
environment and simpler calcs, or pencil and paper, where BX always
means B times X !
