<p>hi, I just bought a ti-89. the manual is 700 pages long, and i don't think i would need to know every function of the calc. can anyone tell me which of the calc's function would be helpful for the math 2c? I will then look specifically in that part of the manual.thank you so much!</p>
<p>YEAH! I'm in the same boat. Heard an 89 titanium would be helpful in getting me closer to an 800 on the Math 2C so i picked one up... I have figured out how to factor, expand, and solve equations and the simutaneous equation solver... However, does anybody know the advantages of the 89 with trig? I cant find any trig features that the 83 doesnt have... is there like a fast way to solve law of cosines? I just preordered this book.... and would suggest u do the same.</p>
<p>yes, I also recently got a TI89 and have no idea how to use it...</p>
<p>help?</p>
<p>mine is the regular ti-89, not titanium. i think i know the book which you are talking about. but will it work?</p>
<p>i think it would be best if someone could list the things ti-89 could do and are helpful to the math 2c. that way, we can just go into the specific section of the manual on TI website. thanks</p>
<p>come on... i know many of u guys know the 89</p>
<p>i second the above comments!! I need to know how to use this think by october for my sat2s...</p>
<p>(pleeeease!!!)</p>
<p>^ same......</p>
<p>I got an 800 on math 2c, you will NOT need to use all the functions on the 89. I only used the auto solver, graphing untiliy, and simplifying utility, and those were just to double check work.</p>
<p>solve(function (in terms of a variable), variable)
like
solve(x^2+235213412412415134.234234123x-234135x^42, x)</p>
<p>check the new TI83-84 book of meylani, it has a special chapter on TI 89; it might help</p>
<p>thank you amacing</p>
<p>where are these functions
(I got this calc from a friend, and so have no such users manual)</p>
<p>amacing, if you want to use the Solve function, you need an EXPRESSION. The thing you listed is an EXPRESSION.</p>
<p>You need solve(x + 5 = 1, x)</p>
<p>You can also find derivatives, etc. but that isn't tested on MathIIC.</p>
<p>be familiar with the solve, factor, expand and graphing functions. thats about it.</p>
