I made this at play practice yesturday
btw.. i missed the bottom segment length.. it should be:
(2(1/3)(1/4)(SquareRoot(2X^2)))
*All Expressions Anti Simplified for sake of those who don't as easily understand lowest terms

Thanks, now I can, ah... apply... this information to... stuff.
Honestly though, I actually do like it. Someone who likes DDR enough to anatomize the arrow.
You could make a nice graffiti stencil with this...

heh... i'm a math freak in general... i like... EVERYTHING... algebra, geometry, trig... i have yet to take calculous... but.. yeah.. its fun.. although... the dyslexia that comes with being good at math is.. interesting...i do actually like everything though.. not just math..=p
I really like making things easy... for the sake of laziness... i typed all the elements into my calculator, assigning the atomic masses to variables representing the symbols... cause right now, in chem, we are doing stuff with mass and molar wait and stuff.. |

Yea...calculus...it sucks...
Now build a peicewise function of it so it can be graphed.BTW, Good jorb, i like. I should have my calc teacher check it for errors, tho...

heh.. i would need a function for every line segment..=/
and all the angles are either 45, 90, or 135... and all right triangles... there shouldn't be any errors =/ .... And trisectors... hehehe... those are fun..

sqrt(2)x is a much better way of saying sqrt(2x^2)
also, arent the arrows rounded at the corners?

no... cause you need to take 2 times x^2 first...=p
the default ones are rounded....
but i didnt' feel like using trig at play practice =p

Because of order of operations, 2x^2 means the same thing as 2(x^2). Thus, sqrt(2x^2) = sqrt(2)*sqrt(x^2) = sqrt(2)x

That function describes the irradiance (R-sub-N) of a given parcel of the atmosphere for any wavelength channel "N" at a specific height (Z-sub-T) as measured by the SAGE III data instrument's spectograph.

Can it be? I have actually stumbled onto an intellegent thread in Chit-Chat? *gasp*
And Calculus is freakin' cool. I love all the theorems. Calculus isn't just about the numbers, mmaaannnnn. Its groovy.
