How useful is the ti-89 on the math 2?

<p>Hmmm... So you press "Zeroes(" and then type in "x^6..." then ")"</p>

<p>And then? I pressed enter and it says missing arguments:(</p>

<p>zeros(x^6,x) which gives {0}</p>

<p>but read the manual that came with the 89. It explains everything very well...</p>

<p>I bought the TI89 from my friend for a good price (it costs 170€ in the shops here), but he didnt have the manual. :(
But I guess I'll find the manual in the internet =) God there is so much to learn in only 5 days -.-</p>

<p>Is the TI89 a graphing calculator?(We don't have that make here, where I live). I spent my whole saturday searching for a graphing calculator, and i didn't find one...
So I guess I'll just have to rely on my good old scientific...</p>

<p>autkcat, try online shops and ebay :)</p>

<p>did you remember to put the argument?
its
zeros((equation),X)<br>
(X is the argument)</p>

<p>Thanks for the advice, ZeDschermen. But there's no way anything i order now will get here in time... unfortunately... and even if it did, how would i learn to use it before june 7?</p>

<p>But be careful when buying an 89- many college professors won't let you use it, because it does too much. Learning this broke my heart, because it meant that I couldn't sell my 84 to earn money towards an 89. which means no 89 for me <em>weeps</em></p>

<p>don't use zeros. </p>

<p>For all equations.</p>

<p>Solve(<em>insert equation here</em>=0, x) if you want zeros, put =anything you want and it'll tell you. Example: Solve((e^3pi/4)/sqr(3x)=5pi, x). </p>

<p>And there ARE questions like that on Math II, it's just not asked the same way. Alot of the times it's like: for what value of x will this equation equal ?</p>

<p>Or for what values of x and y will this system blah blah.</p>

<p>yes, the Ti-89 CAN solve system of equations.</p>
