<p>Does anyone have any suggestions/recommendations for calculator programs that include equations, solvers, etc?</p>
<p>If you have a graphing calculator, you should be fine. If you have a TI-83, 84, NSpire, etc., formulas/inputs that may be useful are:</p>
<p>*nsolve (e.g. nsolve(4x^2 - 6x + 1 = 0, x = 2))</p>
<p>*Linear regression. These do occasionally show up on Math II.</p>
<p>*Binompdf/binomcdf. For example, if you are asked the probability of obtaining at least two heads out of four coin flips (even though it is easy to do by hand).</p>
