I assume the pac mate's calculator is about the same, I know it does sine,
cosine tangent, and quite a few things that are quite complicated. I suppose
in school in the formulas that need such items, scientific calculators are
usually used. One problem is that for a blind person, a talking scientific
calculator costs over $600 itself, that TI one that only spoke when the E
button was pressed and required reprogramming to do so every time the
battery got drained enough. The answer was all it spoke. School had one
then, as it was pretty much required for roots, high exponents, and the
like.
