You have two vectors in the complex plane: ##Z_1=(0,i)## and ##Z_2=(1,0)##. Noting that ##Z_1-Z_2 = (-1,i)##, the magnitude of the... -
bob012345 replied to the thread Insights Fermat's Last Theorem.Could we say his ‘proof’ wasn’t even marginal?

This is nonsense.

bob012345 replied to the thread I Geometry problem of interest with a 3-4-5 triangle.The two solutions with square edges along the triangle sides cut the triangle into either two or three smaller 3-4-5 triangles. The case...

I can recognize a lot of squares with three corners touching the three triangle’s sides while the fourth square’s corner does not touch... -

When the diagonal is vertical, that has ## m=1 ##, and my formula for ## s ## agrees with that result, s=12/11 root(2), but it is not...

bob012345 replied to the thread I Geometry problem of interest with a 3-4-5 triangle.I got the maximum and one relative maximum but missed the minimum. I had the diagonal of the square vertical which gives s=12/11 root(2).

I think I have a solution to this, but I need to double-check my calculations. It was a little tricky computing the size of the square...

bob012345 replied to the thread I Geometry problem of interest with a 3-4-5 triangle.It might be interesting to consider a square inscribed in a 3-4-5 triangle. If the square must touch all three sides, what is the...

@SammyS I agree in post 35 that @bob012345 has a regular octagon. It is in post 46 though that he finally drew it the way I was looking...

Here I have quoted Post#36, where you refer to @bob012345 's figure in Post #35. Rotate bob0.., 's figure by ##22.5^\circ##, ignoring...

bob012345 replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Apparently, this construction, the original square with semi-diagonals as @DaveC426913 drew in post #18, goes back thousands of years...

bob012345 replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Yes, I rounded it to fit the grids of the graph paper from 2.828 to 2.75 since the grids were quarter inch. Made the drawing a lot easier!

This, by the way, is the actual fold template for the origami diamond. You can see that the pseudo-diagonals are now bisections...

@bob012345 Yes, the octagon in the very center is what I was looking for. Excellent. :) That's what I think they were trying to do in...
