Total Posts: 689 | Our Algebra II class has just started these. What I want to know is, is there a program or application out there for the TI-83/84 series that can do logX()? I ask because most of the time we do logarithms with bases other than ten. Log base 2, for example.

Total Posts: 1676 | there's a really simple way to do that.
it involves division... it's been like 8 years since i've done it, so i can't think of it off the top of my head... but it might be:
ln(number)/ln(base)

It is much easier to suggest solutions when you know nothing about the problem. |

1. He was a programmer before he went to math teaching.
2. He didn't seem to care that there was an X-root function on the calc, stopping the mandate for A^1/X-type stuff.
(Actually, I already made the program la tarde pasada. I just didn't think of showing anyone.)
