<p>hmmmm which graphing calculators do guys use while working on physics or maths problems?</p>
<p>I use the TI-89 where I can. Math classes don't usually allow you to use a calculator on tests, so it's in your interest to not use them in HW. In other classes, in my experience, there are no such restrictions.</p>
<p>hmmm so which TI calculator is allowed btw?
and
i see a lot of asian guys with a large screened(the shape of palm) thingy while they are doin maths.Lol i curious as what it is? and whats its use.Does any1 of u knw abt it?</p>
<p>I own a TI-89 but I haven't used it since high school. None of my math classes allows a calculator and my physics courses don't really care about the final numerical value but rather setting up the problem correctly. When I do need a number I usually just use my 2x4 inch pocket calculator. Honestly I can do most calculations in my head though.</p>
<p>same here dude ,even i did differntial calculus and other calculus stuff with just paper and pen ....</p>
<p>Math classes don't usually let you use any sort of calculator. But as was mentioned by JoeJoe5, they aren't testing your ability to crunch numbers but your ability to set up the solution to problems. The number-crunching is usually mental math, but that can include powers, logs, and trig functions.</p>
<p>I only use my TI-89 for number-crunching, you can evaluate rather large expressions quickly with an 89 and it's really easy to check your answer because you can see the expression you typed in a format that resembles what it would like if you wrote it (called "pretty print" or something like that).</p>
<p>TI 89, it is very useful for lab calculation</p>
<p>so all use ti-89 hmmm</p>
<p>I used a TI-83+</p>
<p>I use a TI-89, but it's not necessary at all. I only ever use it for the rare test that allows calculators. I just used google as my calculator for a homework assignment. Type in an expression, and it will evaluate it.</p>
<p>Same TI-83 (not even a plus) that I've used since 7th grade. That makes it... oh man. Fifteen years old.</p>
<p>I know how to use it really well, I'm used to typing quickly on its buttons, and it's always done everything I've needed it to do on a daily basis. Anything computationally crunchy, I've always been able to use Matlab or Mathematica on a lab or work computer. If you're fine with your old graphing calculator, you should really spend the money on beer or pizza.</p>
<p>Or on beer AND pizza =)</p>
<p>Good call!</p>
<p>I hard code all floating point calculations in ASM on my computer.</p>
<p>I use a HP-50G, because its actually a scientific tool rather than a toy like the ti-89T. not to mention the 50g is drastically more powerful compared to the ti-89T.</p>
<p>When your calculator can computer 8000!, come talk to me. Oh thats right the 89T hits its theoretical infinity at 300! and only allows 299!</p>
<p>My method can compute (10000!)!, provided you give me enough floppy disks to write the answer on.</p>
<p>When the forces on the buildings I design get to be (n!) large, you're going to be in as much trouble as I am. And we won't be worried about calculator computational power, I promise.</p>
<p>thank god... i posted this thread....so i wont need to spend 120$ would i? lol
yea so i will go for a regular calculator but... when i see it,u knw the graphing calc,it is just like a diamond for a girl,as that calculator is for me....</p>
<p>bah! i dunno...</p>
<p>My factorial is bigger than yours.</p>
<p>Save your money I have yet to do anything on my TI-89 that I couldn't have done on a 10 dollar calculator.</p>
