I have used a TI-89 for a long while and never come across this problem.
One of my student's calculator: when you ask it to determine a derivative
entered as d(2x^2 +3x,x), I get an answer of just 3, rather than 4x + 3. It
does not matter if you put multiplication signs in between either. Any
thoughts??
