Hello, my friend recently told me that for the SAT II Math 2, one should just buy the TI-89 because allegedly, it can perform many fucntions that the TI-84 cannot.

As such, I'm wondering if anybody has any information/tricks regarding this.

I have used google but cannot find any SAT II Math specific tricks or advantages that the TI-89 has over the TI-84..

Anybody who could shed a bit of light on this question would be highly appreciated.

527Registered User Member1,130Registered User Senior MemberAs far as I know.... we only need calc for:

Matrices/Determinants, Standard Deviation, Extrapolation?

Anything else?

1,295Registered User Senior Member1,130Registered User Senior MemberFor curiosity's sake, what would those functions be? Maybe, I can learn what's too powerful for the TI-89 and write something up for TI-84

117Registered User Junior Member1,130Registered User Senior Membernone of which we need for the Math 2

Any other ideas?

115Registered User Junior MemberFor Math II, the equation solver and expression expanding/factoring capabilites might be helpful.

1,130Registered User Senior MemberBut I see what you mean about the TI-89. But for the MATH 2, there isn't that much calc stuff is there?

2,214Super Moderator Senior Member3-4 questions are often solved ("solve" function, doh) faster on that machine.

I am not saying using TI-84 will prevent you from getting 800.

^lolilaughed - there is no calc on Math 2 you'd need TI-89 for.

In October there was question on maximum, but it was peanuts to answer with sheer graphing and tracing.

I wish TI-89 was a literary device and allowed on Literature. :D

527Registered User Member146Registered User Junior Memberteh 84 is more than enough. the calculus and all in math 2 is so basic that even a 84 is not required. but 84 is perfect for all ur needs. the right blend of smart, speed and simplicity. plus cheaper too.

134Registered User Junior Memberjust to add, i used an 89 and got an 800, and while i would've got an 800 with an 84, it would have taken a lot more effort.
