SAT math level 2 subject test

sage1991 · 08-08-2008, 04:34 PM

Which calculator is the best for the math level 2 subject test? Is the TI-89 good? I heard it was very good for this test if you learned how to use it correctly. I already have a TI-84, but I was wondering if a TI-89 was better.

A TI-84 is more than enough for the Math II subject test. Thats what I used on my test, and I got an 800.

I have a Ti-83

:P nah, they're like the same.

hahaha i HAVE heard that an 89 can be useful for AP calc BC...but seriously
84 is already pretty much overkill for the SAT II

It doesn't really matter as long as you're familiar with the calculator

I used a TI-84 and got an 800. My friend used a TI-89 and also got an 800, and she said that the 89 helped her out a lot. I think it might be helpful if you know how to use it, but I would spend your time reviewing the material rather than trying to figure out a new calculator.

If you know how to use a 89, it will definitely shave seconds off many questions.

um. i use a casio...graphing calculator. but i dont see how it matters...unless:

are matrix problems on there?

anhtimmy · 08-13-2008, 08:43 PM

yes, but they only ask for the det

nominal · 08-13-2008, 09:45 PM

since i dont know what a det is, i guess i DO need to review.

Determinant.

If you have a TI-89 and know how to use it, then it will literally take the test for you. It has a lot of functions, and is very useful on some problems. For instance, on the June 2008 Math 2, there was a question on that made you find the determinant of a 3 by 3 matrix. Thats a pretty time consuming question because you probably have to use either Cramer's Rule or Basket Weaving, both of which waste time and can go completely wrong if you make one menial multiplication or addition error. I used my TI-89 to solve that question, by simply typing in the matrix on my calculator and the det function. Took me about 60 seconds to do all that, but I knew I got it right (btw, the determinant was 0). It also graphs faster, can do limits, can do derivatives/integrals, and solve almost equation. So, if you want an 800, this is the calculator to get.

well i think i need a ti for physics, and i might as well get something that will help me a good amount. shaving seconds off of the math 2 test sounds like fun. i assume the 89 is much more expensive.

I can calculate determinants on my TI-84.

ashraf eassa- how can you calculate determinants on a ti 84? I am not familiar with marticies but I need to be soon as I am taking the test in October.
