There's a bar vertically down the center which is 1 by x. There's another one horizontally which overlaps, so: x + x - x^2. Then you have the 4 triangle bits, each of which have a hypotenuse of x, so you could put them all together (hypotenuses out) to form a square of side x, so: 2x - x^2 + x^2 = 2x. So the only thing outside the octagon is four more little triangles which are exactly the same, so another x^2, and that fills out the original square, so: x^2 (outer triangles) + 2x (horizontal and vertical bars) = 1 (area of original square), so x^2 + 2x - 1 = 0.
That? Makes me want to run screaming. I don't know how you mathy types do it.
Sorry, everybody. I have about a month and a half to cover linear algebra, discrete math, trigonometry, and number theory, so that's pretty much my main focus (especially since I only have the rest of the month before I'm doing two clases as well).

Oh, I think it's fascinating, don't get me wrong. Just that...if it was "Do that or equation or I'll kill you!" I'd be a very dead girl.
I'm not proud of it, but I am a math loser in every way.

It only looks bad because I'm trying to type it. If I could draw it for you, it really wouldn't. I just fiddled with the pieces like a tangram.
tan(theta/pi), on the other hand... Well, I have trig fear. Save the arccotangents!
No, that's very elegant, Emily. Very nice. The kind of thing Euclid would do if he had Descartes to help him, really.
Now I feel like I should change my name so you don't have to jump through hoops to address me.

It's okay, it was kind of fun.

Except Euclid would say, "To apply to a line segment AB a parallelogram similar in area to a given rectilinear figure F and exceeding by a parallelogram similar to a given parallelogram" and I would throw my hands up in disgust and scare my cat.
Er, which is pretty much what happens at bedtime every night.

Yeah. When I see people do math like that, I feel sort of the same as when I look at super thin models. I *know* it's technically a possibility, but I don't know how, and have a hard time believing it's real, even when I'm looking right at it.
did you like the format? cause if so, why care that is a franchise?
Well when I heard it I was all, whoa, great idea, and then I was like, dude, this station really knows me, then I was all down with the guy doing the Jack taglines, and now I'm just feeling like a sucka.
And also, I was willing to overlook a few crappy songs because I figured there was some independent DJ coming down from his pot-break in the back room and realizing he accidently left Madonna's "Holiday" on the playlist and it doesn't seem as funny as it did at the time. Now I suspect the songs are played based on actual surveys and marketing tests. Ugh.
See, but math is like using a vibrator. For the longest time they had us convinced it should only be attempted by people with advanced degrees, but actually you just need some free time and privacy.
