yes they would. that is how you don't fall through your chair.

i thought in the other lesson you said [math]\frac{dy}{dx}=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}[/math] edit: how do you get the "h approaches zero" under "lim"?

they would still be touching at at least one point, so there would be friction.

it will go until friction stops it. what happens when you roll a ball on earth?

spheres aren't entirely sphereical. if you're assuming they are perfect spheres, then it wouldn't move.

it depends where the second is located.

we have an answer http://www.abovetopsecret.com/forum/thread68952/pg1

they wanted me to mail in the last page of it by yesterday. little do they know i got it today. go us postal service!

is it(-1.744,-3.958) and it is a minima?

what if one of them are standing on a planet? then they can tell who is accelerating.

i recently got a letter form the Nouveau Tech Society. http://www.nouveautechsociety.com/BDL1.php they are such losers. i don't even want to know what they want from me. it is probably a cult. it goes on like that for 8 pages. does anyone know anything about this Nouveau Tech Society?

what are they for?

links or at least a description of the experments that "proved" the speed of gravity to that of c?

universe in a nutshell is old pop-sci. it isn't as simple as sphereical or saddle. above critical=+curveature, below=-curvature. if you haven't heard that the universe could be infinite and curved in on itself, then you may want to try harder.

what nasty polynomial?

here is what i have for the first three. haven't started the fourth yet. 1)i)2x+5 ii)-2x+17 iii)[math]\frac{32}{3}x^{\frac{5}{3}}-\sqrt{6}x^{-3}[/math] iv)[math]a^{-2}[/math] 2)i)5 ii)17 iii)[math]\frac{160}{9}x^{\frac{2}{3}}+3\sqrt{6}^{-4}[/math] iv)0 3)i) [math](-\frac{5}{2},-6.25)[/math] ii)[math](\frac{17}{2}, 144.514)[/math] iii)(.001,37.926) iv)[math](a^{-2},a^{-6}+a^4)[/math]

it sound like you are unwillingly playing the role of atlas.

i went back later to finish it for a particle that didn't move at c. i got a formula that says particles UNDER c have imaginary mass. i was under the impression that only tachyons had imaginary mass. what does this mean? [math]m=\frac{h(\sqrt{v^2-c^2})}{{\lambda}c^2}[/math]

it may help if youspecify what you want to be tutored in.

that site is just pseudoscience. the first paragraph of the home page basically says modern astronomy/cosmology is crap.

um, [math]E=mgh+\frac{1}{2}mv^2[/math]. the energy in all positions is the same(neglecting friction which somewhat steals energy by the movement through the air). at the highest point, gravitational potential energy is high, so kinetic is low. at the bottom, gravitational potential is 0 so [math]E=\frac{1}{2}mv^2[/math].

i doubt that it is real. doesn't dna degrade somehat quickly after death? cells break down, ect. why would they break the "bone" in half?
