No problem . Just as an aside, all you really need is a simple scientific calculator. Albeit, a graphing calculator does save a bit of time if you want to use it for graphing and all of that nonsense.
Also, for students who are not completely fluent at solving algebraic equations, the solve function is very helpful. It is the one thing that sets the ti89 apart.
You can put in an expression, like solve(2x+3=5,x) and it spits out the x value. Here, it would say x = 1. You can also put in multiple values, like x, y, etc, and it gives you there value related to each other. It's a very nice feature.
Replies to: Is the ti-89 calculator allowed for the SAT?
Thanks for your answer.
However, you really dont need it on the exam. It would best just to use a ti-83 + etc, just use any calculator you're comfortable with.
Hope this helps you out.
i stand corrected.
