<p>Can someone give me a crash course on using the TI89 to solve DE's? Like finding the general solution and solutions to IVPs... I know you put it in the deSolve(function, x,y) blah blah blah but the answer is never in the right form.</p>
<p>Anyone? know of any websites? Thanks!</p>
<p>learn to integrate and seperate</p>
<p>This might help you out:

<p>my prof doesnt let us use them...89 for diff eq is practically cheating</p>
<p>I just want to use my calc to check my answers on homework. So thank you to boxesarefun for answering the question and not ranting about my practices. </p>
<p>If I didn't know how to do it manually a calculator wouldn't even help because just showing the answer not only gets me a zero for that problem but my prof subtracts points off the total(ie I can get a -1 for a problem).</p>
<p>Thanks again.</p>
<p>ti-89 you ask?</p>
<p>On the home screen, press f3. :)</p>
<p>Why don't you just plug the solution(s) back into the differential equation and see if you get an identity? You are talking about elementary differential equations, right? If not, then my bad.</p>
<p>It's not necessarily cheating. In my class we get long involved problems, and on the AP tests for Calc the open ended problems are many step, and its more a test of concepts, not can you do the nitty gritty work of differentiation.</p>
<p>Well it has its uses in elec.engg. or physics classes where you gotta solve an ODE to get the final answer but the question is not about solving ODEs, but about elec.engg. or physics concepts.</p>
