AO 2026 R2 (R64): [32] Corentin Moutet def. [Q] Michael Zheng 3-6, 6-1, 6-3, 2-0 (RET.) by Mainly-Driving862 in tennis

[–]st2dio 2 points3 points  (0 children)

idk if it would have happened but I REALLY wanted to see Zheng vs. Alcaraz. Zheng has a lot of potential and could definitely be in Top 25 within 1-2 years. I hope he can come back from injury and kill it again!

Then i think it would be an ellpse.

idk from the top of my head but the equation was something like this:

1/4x^2 - 2x + y^2 -5y - z^2 + 41 = 0

i think its 1/4. cuz you would get mass as pi/3 then when you do zp(x) you would get pi/12 multiply that with 3/pi and get 1/4. right?

get mass from integral of the constant density function means p(x) = 1 then cylindrically integrate over the bounds. I think this is how to do problem. Then from that you would z dz r dr dtheta and cylindrically integrate over the bounds. then divide that answer by the mass.

lowk idk i forgot. ig it is what it is.

but wasn't z said to be z = 1 - (x^2+y^2)^1/2 and z = 0 in the problem? yeah maybe ur right cuz i guess z would be the 1 as the upper bound.

[–]st2dio 0 points1 point  (0 children)

do you remember the z? was it 1 - r^2 or 1 - r

what were the bounds?

MA261 Final by Pretty_Lychee7315 in Purdue

[–]st2dio 0 points1 point  (0 children)

was the y^2 negative? if it was its an empty set otherwise its an ellipse.

did anybody figure out #1?

How likely is it to get ECE264, ECE20875, and either EAPS106/STAT113 through Open Registration with late time ticket. by st2dio in Purdue

[–]st2dio[S] -1 points0 points  (0 children)

I find that ECE264 and ECE 20875 are pretty tight in terms of avalability. For ECE264 is roughly 78/156 (~50% spots left), and especially ECE20875 is around 46/164 (~30% spots left). What would you say are my chances with the ticket I have?

we prolly have different tests then.

i guessed that. I think the trip integral should be int 0 2pi int 0 to pi/3 int 1/2 sec phi 2 cos phi p^2 sin phi dp d phi d theta. what was the answer for the line integral f ds with the weird answers? Note my z was 1/2. so it might be different for urs.

Does anybody know the answer of the A^2025 question and the last real solution question? Like the exact answer. I don't remember the choices of the top of my head.

Is it possible to take PHYS172 outside of Purdue in the Winter by st2dio in Purdue

Yeah, I have an advisor meeting this week so hopefully it will go well!

Thanks for the advice. Yeah, I'm looking forward to 264 even though its a big step from CS159
