It would be really sad though cuz this calculator is really good in other aspects like interface and performance. If there is no way I can solve that without turning on CAS, I will just accept it and maybe if required change to another calculator. If only there's a solution for the calculator. But, finding a solution for this calculator would be much easier than fixing the education. I do agree that "it's not HP that you want to petition, it's your education authority". But, mainly, I am asking for solutions to my problem. Aren't only the lowercase functions are CAS? A lot of calculators out there that does not have CAS but still can solve for roots.Ģ) Why does POLYROOT() is uppercase but it is part of CAS. Let me re-state my question:ġ) (In CAS off mode) What is the fastest way to find the roots of a polynomial including imaginary roots. Similarly here, it's not HP that you want to petition, it's your education authority. It's your local government that you want to petition so that they allow the sale of swordfish. There's no point in complaining to the fishmonger, he's only doing what he's told to do. That's like walking into a fishmonger's and complaining to him that you can't buy swordfish because your local government has forbidden the sale of that fish.
There's a function that's part of CAS and you're complaining that it's unavailable when CAS is unavailable, right? (10-24-2020 11:00 AM)grsbanks Wrote: I'm not sure what the problem is here. Basically, I just wanna know if there is a way to find the roots of a polynomial without CAS? IB stands for International Baccalaureate Diploma Programme. However, without CAS, how am I going to solve polynomial equations and find roots? I have seen my friend's calculator that does not have CAS and can solve polynomial equations. It is fine because I can turn on the exam mode. (10-23-2020 04:22 PM)rprosperi Wrote: (10-23-2020 03:03 PM)Amrlxy19 Wrote: Hi, im an IB student, and IB does not allow to use calculators with CAS.

Is there anyone who has experience with IB or any other exams that needs to disable CAS? Because this is may be only the first problem I encounter, so any related experience/story will be really appreciated.Īny help would be appreciated and thanks in advance.ĮDIT: IB stands for International Baccalaureate Diploma Programme.
But right now i am loving this calculator except for the problem above. So, what is the fastest way to solve without using CAS features? Otherwise, I think this calculator will slow me down in exams. But, I am going to use it quite frequently. I know that it is possible to use the function app to sketch the function and find the roots. Hi, im an IB student, and IB does not allow to use calculators with CAS.
