The only thing graphing calculators are really good for are vectors and matricies. But the only way to understand it is if you read the 300 page manual, or do a helluva lot of computer programming.
The only real problem I have with math are vectors. Doing multivariable calc was okay, but messing with all those i,j, and k unit vectors was a bitch. I don't get story problems, vectors, or matricies. I always approach any problem involving statics, dynamics, or physics with linear algebra and some basic trig. It's so much easier just to disregard all units, simplify everything down to a Cartesian coordinate system (polar is great in two dimensions, but you can't really solve for net forces unless you break everything down to a Cartesian plane), and crank everything out with systems of linear equations.
I mean come on, there are very few practical situations that vectors and matricies actually simplify problem solving, unless you're dealing with computational tools (MatLab 6 is great with vectors and matricies, but really slow when it comes to simple mathematical operations).
