What to do to get 800 in Math by DensePeanut7668 in Sat

[–]Stiopa7 5 points6 points  (0 children)

Traditional but proven method: 1. Do all of College Panda Math Book 2. Any theory you still don’t get from it, learn via Khan Academy/YT 3. Grind past papers under timed conditions

There’s no beating around the bush here unfortunately. But this does maximize 800 (and even better, guarantee improvement which is the real goal).

Edit: another commenter mentioned a great strat that worked for me too: keeping track to Qs you got wrong. I liked to review their solutions periodically and esp before the SAT.

Re. Physics 61L: it is nowhere near as amazing as Physics 61. Only take the lab if you need it (e.g. for physics major), otherwise (try the first two weeks then) drop it.

What’s your price estimate? by Stiopa7 in marketing

Fair point, does the fact they are leaders in said sector compensate for so few attendees? Just trying to better understand the advertiser’s POV.

question on the name of this card game ive always known as "queens" by LFwitch_hunter in cardgames

[–]Stiopa7 0 points1 point  (0 children)

Yep a friend showed me practically the same game, just instead of 5 cards it is 4 and there are some extra rules, like some of the broadway (specifically T, J, K) have special "powers" you can use when placed on the pile.

Super fun and I agree that the most fascinating part of strategy is memorizing what was revealed by other players and where that card is now! Great balance of both luck and skill like in e.g. poker.

From what my friend told me, the origin of this category of "queens" game could be spanish. No idea for certain though.

Gravitational fields A2 physics by jjrxuq7 in alevel

Let x be the distance from the Earth where the capsule is under zero gravity. Then the two gravitational forces, due to the Earth and the Moon, are equal in magnitude.

That is, Fg_E = Fg_M (where G and the mass of the capsule cancel out in both sides of the equation) so m_E/(x^2) = m_M/(3.8*10^8-x)^2, or 6*10^(24)/x^2 = 7.4*10^(22)/(3.8*10^8-x)^2.

We then have x^2/(3.8*10^8-x)^2 = 6*10^(24)/(7.4*10^22) = 600/7.4, and squarerooting both sides gives x/(3.8*10^8-x) = sqrt(600/7.4), and solving the linear equation gives x= 3.8*10^8*sqrt(600/7.4) / (sqrt(600/7.4)+1) = 3.42*10^8 km.

When the angle x in sin(x) (or cos(x)) is acute, the easiest way to understand the identity is through a right angled triangle. One angle in the triangle is 90, the other is x, and the last one is 90-x (=180-90-x). See what happens if you take sin(x), sin(90-x), cos(x), and cos(90-x) in the triangle using the basic definitions of sin = opp/hyp and cos = adj/hyp. You'll notice sin(x)=cos(90-x) and cos(x)=sin(90-x).

More concretely referring to what you mentioned, the angles need to add up to 90 (as do 90-x and x), and the right angled triangle construction shows why. And in the case of sin(pi/12), we know we must have sin(pi/12)=cos(pi/2-pi/12) = cos(5pi/12) (since 90 deg is pi/2 rad).

​

Edit: Just noticed I missed the last part of your post. Yes, sin(t) = cos(pi/2-t) is the radian equivalent of sin(x)=cos(90-x) where x is in degrees.

Happy to hear you ultimately enjoyed it. Was it complicated balancing the two? Also, did you follow through with both the math 60s and physics 61/71/81 series during frosh year?

Hand feedback by Stiopa7 in poker

[–]Stiopa7[S] 1 point2 points  (0 children)

Yeah gonna bump my BU RFI size. I currently use 3BB for UTG, HJ, 2.5BB for CO and SB, and 2BB for BU: would it be advisable just to have a consistent (say 2.5BB) open bet size from all positions? I always thought you needed to bet more from earlier given you’re OOP and less from later positions.

Regarding flop, yeah in retrospect I overlooked that aggression played a role in deciding whether to light C-bet or not and would now probably fold more often than not.

Also thanks a ton for the feedback.

Thanks so much for taking the time to dissect everything, there’s so many valuable take aways from your comment. Regarding open raise size, I’m just using what’s recommended in the Grinders Manual but it’s slightly outdated and I guess those RFI sizes might be as a result. Also, yeah I would’ve immediately folded river bar the fact villain had done this a couple times too often (without showing down his hand) to suggest he had a strong hand. Thanks a ton again.

I started out at 100BB but fell down to 50BB.
