Rotate 2a (Advanced)


Dan Anderson (@dandersod)



On to the Challenge!

Can you create the following graph using or some other graphing tool? If you’re victorious, leave us a note in the comments when you’re done.

Hint: consider changing a normal ellipse to polar form, and then adding/subtracting to theta to rotate. This graph was graphed in Cartesian form (x’s and y’s). Bonus: use trig addition of angles formulas!

  1. If you translate the ellipse a bit so the center of rotation is inside the ellipse but not on the ellipse’s dead center, and if you kept the graphs after each rotations rather than erase them, you will get a Christmas wreath. I’ve seen it done but can’t find the source.
