cos(1/x)

For the next update:

(weird number on y axis 000000095367432 and problem with infinity with y=x^(-1), maybe the solution might be to auto-switch to limited precision when reaching infinities such as the vibrancy of a function like cos(1/x) in the area of 0, but I just guess. I´m sure you can fix that

I just see your other Grapher, the A&G, can do it: http://666kb.com/i/c0ed8yq36l0qgvzwa.png

The 000000095367432 is probably because you zoomed in too much. I think the left portion of that number is missing. It was probably a small number like 0.000000095367432. Zooming out should have fixed it.

I just tried plotting the function y=x^(-1) and got this in Graphing Calculator 3D:

You are right that y=cos(1/x) cannot be plotted due to division by zero. It shouldn't happen and we will fix it in the next release. Thanks for reporting it.
