<p>I have a Ti84. You can plug in i into the equation by hitting second (.) the decimal button. When I graph it though, nothing shows up on the screen, when I look at the table it just says error for everything. Is this just a TI84 thing?</p>
<p>Tips before the test? I'd say just relax. As long as you know how to get your calculator to do things for you, you're all set :)</p>
<p>Some more tricks...</p>
<p>For recursive equations like t0 = (constant) .... t n+1 (sub) = e^t0 + rt2</p>
<p>You can just put in x store -> (constant)</p>
<p>then type in x for t0 into the next equation and press enter the amount of times for the # of t you want.</p>
<p>Sorry if that wasn't clear. I found it to be very helpful.</p>
<p>Yeah that didn't make sense at all.</p>
<p>^ I can't use subunits ):</p>
<p>Anyways, with recursive rules. You can set your t0 (first recursive) to store as X. Then set up a func like</p>
<p>rt ( 2 + Ans) where Ans is t0 and then press enter and enter to redo the function (recursive "Ans" use)</p>
<p>Anyone try this one <em>without</em> a calculator?</p>
