<p>hey i was wondering what kind of graphing calculators are good for math courses at ucla, like for example math31a and math31b. are ti83's good or should i get a new 89? also if i were to take the math placement exam, should i need to bring a graphing calculator or just plain scientific one?</p>
<p>you'll probably only need a scientific calculator for the placement exam. as for 31a and 31b... if you get lucky, your professor will let you use a scientific calculator on exams and if you're REALLY lucky, your professor will allow you to use a graphing calculator on exams. out of the four math classes that i've taken here (math1, calc 31a, 31b, 32a) only one actually allowed us to use them. so, i honestly wouldn't worry about buying a brand new caculator - whatever you currently have is probably fine.</p>
<p>For lower div math, what you already have is usually fine. Not all professors even let you use calculators on tests. On some upper div EE and math courses though, TI-89s really help make things a lot easier, so depending on your major you may consider upgrading.</p>
<p>If you get a prof that lets you use graphing calcs on tests then definitly buy a TI-89. The symbolic integration/differentiation is such a huge help. But chances are you won't, so I wouldn't buy anything just yet.</p>
<p>I never got to use a calculator on my tests... so I'd just borrow my friends' TI 83s for homework.</p>
<p>o wow calculators arent allowed in ucla math classeS? ive used a calculator all 4 years of high school...</p>
<p>I took 31b and we were not allowed a calculator on tests. I guess there are issues of people storing formulas etc on their calculator memories.</p>
<p>aww, i find it like impossible to do math without a calculator :( its like part of me. i mean, are the tests possible to do without calculators because my high skoo exams definitely were not...</p>
<p>Interesting... my high school math teacher, who I had for 3 years, never let us use calculators on exams, saying that we would thank him after going to college. I can finally understand why.</p>
<p>Graphing calculators are not allowed for the Math 31A series or the Stats 110A series.
Scientific calculators are sometimes allowed, however. :rolleyes:</p>
<p>i use an abacus (silver version) at school and im pretty comfortable with it</p>
<p>so if graphing calculators are not allowed and scientific are only allowed sometimes, are the tests pretty hard or are the numbers they give you fairly simple to do without a calculator? do you guys use graphing calculators on he homework or what?</p>
<p>for the most part numbers aren't too terrible. most professors aim to test your knowledge of the concepts of the class rather than your ability to add and subtract. though obviously you'll have to do computations but it should be doable without a calculator.</p>
<p>Yea, the tests are designed so that you don't need a calculator, though some people are used to being dependent on one so it may hurt them a bit at first. My calc teacher in high school didn't allow us to use a calculator on tests so the adjustment to college was pretty easy.</p>
<p>For those at UCLA right now, what kind (model) of calculator do you use for math classes?</p>
<p>[list=0][<em>]Sharp EL-520V scientific calculator
[</em>]Texas Instruments TI-83 Plus graphing calculator[/list]</p>
<p>I use a TI-83 Plus, it's probably the most common here.</p>
<p>brandnew, is a TI-83 plus sufficient for you? is it good for whatever you are majoring in? (i dink you are buz-econ right?)</p>
<p>what kind of calculators do you guys use for pre biz econ?</p>
<p>Calculators aren't allowed in the Biz-Econ prerequisite classes, due to rampant cheating by storing equations in them. The given values in the midterms and finals are thus simple enough that you ought to be able to solve the equations manually. Also, in the event that complicated numbers are used on midterms and finals (e.g. Econ 101) the professor will hand out a large table of pre-computed exponents and multiplication/division values for reference. :rolleyes:</p>
