[TIB] Re: converting slope to degrees



Because 86 is evenly divisible by 2?
BTW the 89 has a glitch... or at least a really aggravating pet peeve.  When
you type: 5(4) that is == 20 because of "implied" multiplication, but what
if you enter x(x), well you get an error!  If you type y1=x(x+1) and hit
enter, it accepts it, but if you graph, it says it's not a function... then
if you try that on the 83+ guess what... it likes it... Running AMS 2.03
