Another way to solve it: When is it justified to drop 'es' in a sentence? Fascinating that the optimal solutions should have less symmetry than the setup! Is there a “phase transition” where the optimal solution switches its form? Your work appears to show that, as a function of $a$, where fixed $b=1$, $$L = a+\sqrt3$$is the shortest collection of roads linking the four towns. Let’s say you’re contracted to build roads to connect four towns that are at the corners of an imaginary square with sides 1 mile. The question is then asked: what length of road(s) is necessary to connect them? Find the area of a triangle with one side and 3 angles given. Also you can move only up, down, left and right. Now this is a fairly special property of arranging four points in this way: there are only 2 distinct distances. For the length, I used$$L = 4\sqrt{\left(\frac{1}{2}\right)^2 + x^2} + (1 - 2x)$$ Finding the derivative of $L$ and setting it equal to zero, I found that $$x = \frac{1}{2\sqrt{3}}$$ so $$L = 1 + \sqrt{3}$$, As for the angle, $$\tan \left(\frac{\theta}{2}\right) = \frac{1}{2x}$$ so $$\theta = 2\arctan(\sqrt{3}) = 120^{\circ}$$. ... bottom square is d1. Well, we have 10 choices for the first 'right' to convert (see the combinations article). When I shared the Here’s My Heart Pattern I mentioned that I had made a number of my own granny squares. Introduction Solvability Rules ... the player is able to guide the way odd and even squares are divided up among players. Three edges meet in a corner and stand perpendicularly on each other in pairs. Out-of-square corners -- those that don't form a perfect 90-degree angle -- are common when installing cabinets. Thank you for pointing that out. Demonstration of minimum connector of the corners of a square. (Most people would say a square, but that is wrong - see diagram 2 below.) Do you get to experience the "earthly joys" after Moksha, if you did not get to experience them before attaining Moksha? Since setting the derivative equal to $0$ gives the same minimum value of $x=\frac{1}{2\sqrt3}$ for all lengths of the rectangle, the four corner roads do not change in length or angle with increasing $a$. I was pleased with the rugged weight of the steel and the connector bolts. This problem is from MIT's Single Variable Calculus course. Set four 2-by-4 stakes in the ground to represent the four corner posts. We can find this by computing 2*tan-1 (.5/X) = 119.9997674 or 120 degrees.
