Hi , I'm entering college this fall majoring in mechanical engineering and I need a graphing calculator. However , I am unsure of which one to buy. These calculators are quite costly so I want to be sure that I am getting the right one. I simply want a calculator that will be able to function through any math related courses. Could someone who is going through or has gone through mechanical engineering give me some advice here? Thanks in advance. Note : My apologies if this is in the wrong forums.
