I m trying to understand your problem, but i can't see our point. The graphs of the functions seems to be ok. on equation (1), f is negative from (-\infty,0) and F is decreasing on that interval. And also, f is positive on (0,+\infty) and F is increasing. Same is true for the second one. I...

thanks for the advice... id better study more!

what can be the reasons why the plant has the lowest rare of absorption in a green spectrum? white light compose all colors and one of them is green... organisms find their way to survive... there is nothing to lose if we try!

Mathematics says this wrong because it defined something that makes it wrong. mathematics defined everything, but logic can never be defined. its our mind that makes logic!

simple problem for you! here's a simple homework problem! a monkey is on a branch of a tree and a hunter aims with his rifle. at that moment when the hunter pulls the trigger, the monkey fell. will the monkey be shot? assuming the height of the tree is 10 m.. and the hunter is 20m from the...

Lets try arguing in not mathematical terms but logical reasoning. if a number x is divided by any number n, it means giving every individual n a single part from x... if our number is zero how are we going to divide x to zero individuals...? we have a x objects to be divided among no one...

generouge thanks for the point, but try clicking this link and look for the graph http://scifun.chem.wisc.edu/chemweek/CHLRPHYL/Chlrphyl.html green has the lowest percentage of absorption.. why? try figuring it out!

in physics sense, something is green because it absorbs any collor except green, when something is black, it absorbs all colors.. eventually totally using up energy given by the sun. i know not all plants are green, but majority are green... say, a plant is red, it absorbs all colors but...

THANKS If that be the case humans can alter the composition of the chloropyll to improve its efficiency. i cannot really understand ur point...

pnaj thanks for the info... i got that wrong, it must've been nonterminating and non-recurring/nonrepeating... warren ur right 22/7 is just a crude estimation of pi, but i used 22/7 to show that pi has an exact value, not infinity.. the topic is about pi being an infinite. thanks, by...

What do u mean pi is infinite? the value itself or the digit? if u are talking about the digits, its infinite because it is an irrational number, meaning unending digits. the value itself is not infinite because it has an exact value (22/7). its common sense to say that!peace!

Yeah i get it, chlorophyll is green, and physics has nothing to do with that... if a plant then is exposed to a green light it will not undergo photosynthesis because is reflects green color and eventually not absorbing any energy. is this true?

zero makes mathematics full of identities and definitions...

i have avery simple question that has been bothering me since my childhood. why are plants green? an object is green because it absorbs all colors except green or combinations of colors forming green... what is in the green color that plants do not absorb? why are plants not black so that it can...
