I went camping on the weekend and a friend of mine who is a builder
asked me many questions on geometry as they apply to his every day work
- - most of which I could answer.
However, there was one that I couldn't and I am having trouble googling
a solution (for lack of keywords?). I'm hoping a fellow Haskeller could
help me out (in Haskell of course).
The problem is finding the unknown x from the two knowns a and b in the
given image below (excuse my Microsoft Paintbrush skills). I may have
misunderstood his problem (we were drawing in dirt) and actually, it is
the straight line between the two points on the circumference that are
known and not the specified 'b', but I figure I could derive one
solution from another if I have misunderstood him.
Here is my image:
Thanks for any tips or keywords with which to google!
