Homework Statement
I can repeat the proof, but then I won't understand it.
How do I prove that an open interval like (1,2) is open?Homework Equations
I know it has something to do with neighbourhood with a given epsilon, but I don't really get what a neighbourhood is, I have a maybe rough...
yes, I am looking an answer that does not involve the word "quantum".
So I don't get why that portion is there, is it some sort of bad question making?
First of all this is not a HW question, I already "handed" the assignment in and its graded
There was this question on my assignment, it asked questions off of a graph that had distance on the x-axis and energy on the y axis.
The potential energy was a curve, and basically took up the entire...
I asked my prof a question, and this is what he answered
"Vectors can't be negative; only components can be negative. (Only scalars can be negative, and components are scalars.) Vectors can be only zero or non-zero"
can someone explain this to me? I have the feeling that everything I've...
lets take the situation of a traveling toy car with 1kg of mass...
If the maximum force of friction between the car and the road is, let's say, 1N, then is it possible for the car to have >1m/s^2 acceleration?
Which one is a more accurate representation of the image? (i.e. what we see with our own eye)
I've read that camera's actually flatten out the 3d image, but I have no clue what the consequence of this would be, while I do know that mirrors flip the image but I think that's the only thing that...
the question gave actual numbers, I just replaced it so that I don't feel like I'm cheating...
I think I figured it out the proof and managed to finish the assignment with minor mistakes because I still couldn't figure out what the question was REALLY asking me to do, I basically just...
thanks, but i read the proof on the link, schaum's outline and my notes... and I still don't get it...
but really, what is the "beginning decimals of a number"? so... if i have 0.63434143 the beginning decimal is 6? >.<
also if I'm understanding the question correctly is it really just...
Homework Statement
In the proof that there are uncountably many real numbers between 0 and 1, one constructs a real number that turns out to be different from all the real numbers on a given (countable) list. Suppose now that the following are the first few real numbers that are on a countable...
as far as I know vitamin B's are important cofactors for energy generation thiamine..pyruvate dehydrogenase catalyzed conversion of pyruvate to acetyl CoA, the other Bs are related to reactions involving the electron carriers, i forgot wat b12 did
but deficiency in thiamine leads to memory loss...
