yes!
i'm going to test it, we have vectorial marh in maths period:)
i think i'll troll a litttle bit but is also very usefull thought (xd)
EDIT:
we don't have vectorial math this school year
as sorunome said, the calculator crashes posting a command in the prog editor(i was bored in math period so i tried it out)
there are just two ways to quit the vector menu: by pressing 2nd * quit or choosing an optioon. this is annoying because i'm not used to quit menu's this way.
but all in all it lookes fine to me, i just need knowledge in vectorial math.
