<p>Bone…octave is basically the opensource version of matlab. Most m-files run pretty much unaltered.</p>
<p>I love the HP 50g Graphing Calculator</p>
<p>+1 50G.</p>
<p>takes a while to learn, but when you read amazon reviews of ppl needing a replacement calculator after 10-20years from their old HP, it speaks a lot.</p>
<p>Mathematica?</p>
<p>How dare you say that word.</p>
<p>lmao@hadsed</p>
<p>honestly now that I think about it…I never learned to use a graphing calculator. I just used pencil and paper.</p>
<p>I have taken about 2 years of college eng classes (i dropped out because I couldnt decide what i wanted to major in). calc 3, diff equations, chemistry… u dont “need” a graphing calc. A good ole TI 36 scientific will last you and get you A’s in class. </p>
<p>Dont use the calculators to do the work for you, use them to check your work as you learn it. </p>
<p>The TI’s now have RPN, how good it is, i don’t know. I bought a 50g to have something not everyone else has. Its a good calculator but so are the TI’s. what ever gets the jobs done.</p>
<p>RPN destroys my brain.</p>
<p>So far in my 1 year as an engineering major at Clemson:</p>
<p>-I have not been allowed to use a calculator in any math classes
-I was only allowed to use FE approved calculators on engineering exams (which don’t include graphing calculators)</p>
<p>Currently, I haven’t touched my graphing calculator in one year (I think the screen is busted anyways). I have a Casio FX-115 since it helps me in Statics solve simultaneous equations and it seems to work out well.</p>
