<p>Hi,</p>

<p>I'm going to take the Math IIC in June. I've been getting familiar with the TI 89Titanium, but I've still got a lot to learn. The manual that comes with it is not very helpful for what I need. Could anybody point me out to a website that shows the crucial things to know how to use? All I can seem to find on ticalc.org are games. </p>

<p>For instance, I have no idea what keys to press to find the nth root of something, besides the square root. Also, how do you graph circles?</p>

<p>Help would be much appreciated.
Thanks.</p>

<p>i don't know how to find the nth root of something but i always write the root as a power. that's easy and it always works</p>

<p>sorry i don't know where to find a manual.</p>

<p>To take the nth root, just take the number to the (1/nth) power
I haven't actually tried to find the nth root, but that's a workaround. Once you get used to the intricacies, you won't be able to use any other calculator.</p>
