Exactly. I imagine the periods of growth over summer, (and no growth over winter?) would somehow be evident within the fossil structure? But my...
Hello, I was wondering, If you look at a plant fossil, what characteristics of it can be used to identify whether it came from a perennial plant,...
Ah Fednis, I wish I could appreciate the beauty of what you just did... I will! I must! Where could I attain the mathematical knowledge to understand...
I was thinking there, if I was really pumped up for my physics exam, we could say the rate at which I write words is proportional to the number I...
thank you, yes, i see... that is a rather nice way of explaining it. however i do fear that i will my mind will falter me, and this question will...
I can never get my head round these :( if you have a string of beads, for example... and this string of beads is made up of two colours, how many...
aaah, i had that idea... i thought there was something i was missing but alright, thank you!
so, \frac{dh}{dt} = -k\sqrt h and \frac{1}{\sqrt h} dh = -k dt intergrating both sides, i get 2 \sqrt h = -kt + c if only this 2 wasn't...
Yes it is like black magic! I still have no idea how you did that with the substitution, but I found an even better way after staring at it for...
"Water flows out of a tank such that the depth h metres of water in the tank falls at a rate which is proportional to the square root of h "...
ah here we go, bascially, what is this??? \Large \int 4xe^{x^2}
Ok, I know you do this by parts but i don't see how... how do you integrate (4x)(e^[x squared]) and apologies, i still have no idea how to write...
Currently, does it exist or not?
awh brilliant! thank you! been plaguing my mind for like 2 months, that's such a nice step! aaaawh! Also, i read the 'degree' of a non-zero...
*if someone could link me to a guide on how to use those really really cool alegra notation thingys it would be a great help but yeah, the proof...
I've now read that they had axioms in their system that stopped sets appearing that were too 'big'. Can anyone tell me how?
I'm sure wikipedia does a great job of explaining this to all you guys, but i can't understand it. I know that this set theory has axioms to avoid...
thanks for all your help guys i think i get it now :)
i'm starting to get a feel for this, thanks for your help so far guys :) so... the apropos slits only allow light to travel through in one plane,...
well now i have a new idea of light: it's actually two waves! Ok, these waves vibrate at the same frequency as each other because they are one...
