but those programmes will be deleted when you reset and make it to "Press-to-Test mode" so there's no use in the end. (unless you want to use it for homework, classwork etc)

do you know you can solve polynomial functions using your GDC? I've only figured that out like in my second semester of IB1... so in case if you don't know, I can share how to.

Oh wow, would you mind sharing?

And IB2 students keep talking about how easy it is to solve equations on it. How do you solve equations?

actually I use TI-Nspire so not sure if the steps will be the same, but here's how I do it:

from the calculator,

select Menu Algebra (3)

select Polynomial Tools (3)

select Find Roots of Polynomial (1)

insert the degree (2 for quadratic, 3 for cubic, etc)

choose Real Roots

click OK

the general form of the equation will appear. insert the constants.

click OK

press enter

the roots will appear in brackets
