I’ve been using a graphing calculator for like 4 years, and I’ve learned how to graph really neat stuff; and how to program your calculator to graph shapes for you with only the vertices of the points.

Try putting this into your calculator:

y1=cos(1x)+5

y2=cos(2x)+4

y3=cos(3x)+3

y4=cos(3.5x)+2.5

y5=1.5

y6=sin(1x)-2

y7=sin(1x)-4

y8=sin(1x)-6

y9=sin(1x)-8

y0=-9.5

Default=Circle(10,10,4)

Axes=Off

ZStandard=On

This makes a nice landscape of some mountains, a lake, and a sun!

Or try putting this in instead:

y1=5x^-1

y2=4x^-1

y3=3x^-1

y4=2x^-1

y5=x^-1

y6=-5x^-1

y7=-4x^-1

y8=-3x^-1

y9=-2x^-1

y0=-x^-1

Default=

Axes=On/Off

ZStandard=On

This makes a nice diamond picture!

Or perhaps something to do with making shapes:

There you have a nice triangle program!

Do you know of any neat stuffs?

Edit; fixed.
