<p>I'm not very good with my 89. So i have a couple of questions that i've been seeing on the SAT IIc
1 Is there an inverse function on the calculator, if so where? I was looking for something where if u type x-1 and ask for the inverse, it would give u the answer.
2 How do you put in log bases when calculating logs. i was wondering if it was possible. For example log(n)(x-5)(and then in really small numbers next to the "g" in log would be a number" how do i get that number in there. Is it even possible.
3 Where is the matrix function</p>
<p>I know its a lot but plz answer as much as u can. I mainly just want 1 and 2.</p>
