i was wondering what you meant by distinct? distinct = they explicitly state that x,y is a specific number? like (3,5) is distinct and (v,a) is not?
sorry for so much questions, i just don't get why I am not getting it =/ is there an easier way for you to explain it? i feel really stupied...
so in summary if i see for example (1,2) (2,1) it is not anti symmetric but it is symmetric. and if i never see a pattern with (x,y) ex (1,2) and (y,x) (2,1) then it is not anti symmetric. is that right so far?
can u give me an example where it is anti symmetric and symmetric?
okay so i have looked up things online and they when other ppl explain it it still doesn't make sense. I am working on a few specific problems.
R = {(2,1),(3,1),(3,2),(4,1),(4,2),(4,3)}
the book says this is antisysmetric by sayingthat this relation has no pair of elements a and b with a...
Homework Statement
if a freely falling body starts from rest, then its displacement is given by s = (1/2) g(t^2). let the velocity after a time T be vsubt. Show that if we compute the average of the velocities with respect to t we get vsubave = (1/2)vsubt, but if we compute the average of...

Hello, this is the solution to a problem that i am doing and the only thing i am confused about is why the
C1 in the third step is = to − 1/2 ln 2 √3 as stated in the last line.
=√3/2 sec θ − 1/2 ln |sec θ + tanθ| + C1
that is all i am confused about but i get...

okay so i know how to do this but when i tried substitution putting 3t=u and (1/3)du= dt i always came with the the wrong coefficient at the end with the answer and so i would multiply it...
Question Details:
Is CO paramagnetic or diamagnetic? i put diamagnetic because there are no lone paris is that corrects?
and
If CO gained one election, becoming CO^-, would the bond become weaker or stronger? i believe that the bond would become weaker since there is one lone pari and it...
