If I plot Y=sin(95X) on my TI-84 plus silver edition with window settings Xmin=0, Xmax=2π, the graph looks exactly like the regular sine function Y=sin(X).

If you graph the same thing on a TI-84 plus CE calculator however, they do not look the same. Instead you have to make a graph of Y=sin(133X).

What are these calculators doing? What difference between the calculators does this reveal?

Thanks for Nice and Informative Post. This article is really contains lot more information about This Topic gmail login
