The interesting feature about these two pages is the combination of mathematical formulas, text and a very detailed drawing. The drawing has a very precise geometry and is well calculated which I find very impressing. Also that the drawing doesn’t only contain a well constructed geometry part but also a design part is very appealing.

On these two pages I find the mathematical formulas which are in the middle of the text very interesting. There is no reference to a picture it just appears in the middle of the text. This makes these two pages interesting.
