  1. #Rotating a #Point about the origin, through some #Angle θ is something that is taught in school #maths class, usually in #CartesianCoordinates, by multiplying the #Coordinates by a the rotation #Transformation #Matrix. What’s not generally taught is that you can apply the same transformation to any #Function y=f(x). All you need to do is replace
    x by xcosθ + ysinθ
    and y by -xsinθ+ysinθ.

  11. My wife was looking at the properties of #ellipses such as the one where the sum of the distance of all points on the #ellipse from the two foci are the same and how that relates to the standard equation of an ellipse. I wrote these notes up neatly using #LaTeX to explain the relationship.

    To put it up here, I converted the #PostScript pages to #PNG format using #GNU #Gimp and the figure was produced using #Tgif.
