If were once apes, and we evolved to match our needs, like bigger feet to stand on our legs and so on.... why did humans start to grow long hair? what was the social or environmental need that made us evolve into needing long hair?

For now * = theta
A. tan * + cot * = sec*csc*
B. 1-2sin^2* = 2cos*-1
C. (cos * - sin*)^2 + 2sin*cos* = 1
D. cos^4* - sin^4* = cos^2* - sin^2*
E. cos^ 2* - sin^2* = 1-tan^2* / 1+tan^2*
F. (sec* - tan *)^2 = 1- sin* / 1+sin*
G.(tan * / 1- cot*) + (cot* / 1- tan*) = 1+tan* + cot*
H. (1+tan* / 1-tan*) = (cos* + sin* / cos* - sin*)
I. (sin* / csc* - 1) - (sin* / cot^2) = tan^2*

Try and answer...thnx!

Let a ray of ligth is moving along the z axis away from origin of some inertial frame of reference 'S'. The frame 'S' is moving with speed of light along z axis w.r.t stationary Frame 'T'.Then the ligth should appear stationery to the observer in the S. Then why einstien called speed of light universal constant. Why the speed of light is not relative?. Also we can put this phenomena in a way that time is runing slower. But what when 'S' is moving alog -z axis.Then the ray of ligth should appear at 2c speed or the time is runing faster is it so?

If the first pair begin breeding in march and are capeable of a litter averaging 5, of which two are female,every month through to the end of september and each successive female of each litter reaches maturity and begins breeding at 4 months of age what will be the total number of offspring in one season, allowing for a 50% mortality rate on each litter. Only three days after producing a litter a rabbit can be pregnant again.

if a moron met a banker and he didn't have shoes, then his sister was a banana and the sun shoots the moon.. but, if a soldier dies in heaven and a worm sucks the floor, then catapillars don't crumble when cookies run the battleships and mustard doesn't jump.
so, if you think marshmellows are equal to the trucks , then you did not consider moon pies drive the bus.
us brainy types love to think and love thought puzzles. try it. write jibberish but do it well. sentences must connect and the paragraph must be grammicaly correct. if you are are really good at it then the paragraph almost makes sense but of course it can't. that's not allowed. i hope i find some that will try it and answer me. they can be funny as hell.

What percentage of the atmosphere is CO2?

I would like to get a feel for what the average person (who doesn't already know the true figures) thinks the percentage of carbon dioxide in the atmosphere is.

We are being bombarded with hype from the global warming scare mongerers about rising CO2 levels, so what do you think the figures are.

Please, please, please, if you know the answer, or have looked it up, don't post the true figure here.

Thanks.
