I'm a Senior In High School. I got this calculator earlier this year since I plan to be a dual major in Physics and Applied Mathematics. I was just wondering how I can get it to graph 3-dimensionally. I can't get it to enter 3-D Graphing mode, my CAS and OS are up to date and It works on the calculator software for my computer. I've read the manual completely and cannot get it to graph in 3-D, any help?
