Question 1208023
.
Suppose that you have a rectangular field that requires watering. Your watering system consists of an arm 
of variable length that rotates so that the watering pattern is a circle. Decide where to position the arm 
and what length it should be so that the entire field is watered most efficiently. 
When does it become desirable to use more than one arm?
Hint:
Use a rectangular coordinate system positioned as shown in the figures.
Write equations for the circle(s) swept out by the watering arm(s).

Hello, the HINT to the problem instructs me to


"Use a rectangular coordinate system positioned as shown in the figures."


But the post does not provide neither figures nor their descriptions nor references/links to them.



Are you serios by posting one part of the problem and hiding other parts ? ? ? ?
