picture of spiral]1I am seeking to construct a spiral with the constraints shown in the picture. The problem is that I have not covered polar co-ordinates and I am quite bogged down in understanding logarithmic spirals.
the main constraints of the spiral would be:
- 0.15m from center point to start of spiral (apologies if I am butchering nomenclature)
- 0.3m to the end of the spiral
- that between the two points an angle of 30 degrees
- that the distance between the edge of the spiral and the center point decrease linearly from 0.3m to 0.15m.
alternatively could someone suggest a good text book or suggest how to solve this problem?
