Like.
Thanks very much, Gavron! I see my error now. I had not rid myself of my prejudice that isomorphism preserved all structures; I... -

Thanks, Gavran, but apparently I did not express myself very well. Let me try again. First, if I understand your post correctly (but...

GGavran reacted to Charles Link's post in the thread Undergrad Trigonometry problem of interest with Like.
Some of it depends upon who the audience is. If you have a construction worker building something, he'll know immediately what a 90...

GGavran reacted to bob012345's post in the thread High School More similar triangle problems with Like.
The way to determine ##(a,b)## uniquely is to pick an angle ##\phi##. Then we have ##b=2tan(\phi)## and ##a=4/tan(\phi)##. As ##\phi##...
