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...

i was confused about what the cardinality of the set {1,2,2,3,3,1,1,1} is? is it 8 or is it 3?

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...

what am i doing wrong?

what am i doing wrong here? its an easy problem but what the heck am i doing wrong? [b]1. The

Homework Statement 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...

i didn't need to change it because i just plugged back in the variables u with 3t. just wondering it should be correct even if i substitute right?

Homework Statement intergral from pi to 0. of (sin(3t)dt)^4 The Attempt at a Solution 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...

Homework Statement when the sun is directly overhead, a hawk dives towards the ground with a constant velocity of 5.00m/s at 60.0 degrees below the horizontal. calculate the speed of its shadow on the level ground. Homework Equations sin rule The Attempt at a Solution so...

A particle moves along the c axis. its position is given by the equation x = 2+3t-4t^2, with x in meters and t in seconds. Determine (a) its position when it changes direction and )b) its velocity when it returns to the position it had at t = 0. i understand how to get (a) but for (b) I am...

Homework Statement i am have to approximate the area under the curve using left endpoints. Homework Equations y= squr(x+2) on [1,4], n =16 The Attempt at a Solution i have the change in x to be 3/16 using (b-a)/n i also found my xsubi to be (1+3i/16) using xsubi = xsubo + i(chang in x). then...
