partial derivatives using calculus made easy ti89

Maple possesses significance among mathematical calculation systems and can be considered a leading tool in the CAS field.

The rapid computations and the visually appealing graphical interface of the program render creative research possible. That's why I knew the inflection point method, and a few other alternative methods that I have mentioned in class that make things much easier, than long traditional tiresome ways.The computer algebra system (CAS) has been widely employed in mathematical and scientific studies. I think intuitively, which is different than someone who thinks in terms of.dooo doooo doooo, whats the next step.dooo dooo dooo. My point is that I find it unnecessary to hand write every single written step, and I'm much better at getting the answer than remembering a minute single step. I'm already doing diffEQ, calc II and calc III the shit is not complicated And I can use my calculator on all of it that I've done. When you start going up to higher level math, your calculator will be pretty useless to you if you don't know wtf you are doing.

It's like telling someone who can use an abacus, is allowed to use an abacus, that he is wrong getting the correct answer through an abacus. But, to mark off points when I can get the correct answer using allowed tools, then that's fucking retarded. If she didn't want to give me partial credit when I got the question wrong, fine, that's my responsibility. If she doesn't want calculator work then she could say no calculators, fine, but that isn't the case.

Given how long her exams are I find it absolutely ridiculous that if I can find an easier, quicker, and smarter way to do things that I actually get marked WRONG for finding alternative ways. Lastly, she wants step by step work on shit EASILY computed on a calculator, like determinants of matrixes, border hessian matrixes, etc. She seriously DID NOT KNOW that the inflection point of a cubic function is always the extremum of the 1st derivative, which would be the point of decreasing returns to scale. She literally wants me to do it her way even though my way is mathematically correct.

I do know what is going on (I got a 100% on my business calc class, but this lady is nuts), I did it by hand, but because I explained it by inflection point (which is correct), she marked me wrong because she is an asian bitch.
