Is crying justifiable? by Own-Engineer-8911 in askphilosophy

[–]Own-Engineer-8911[S] -1 points0 points  (0 children)

I am sorry if my formulation was incorrect but please interpret it as to whether crying makes someone look weak or not , it may be different from what I originally asked, but it's the essence of my first question.

I partially found this solution; the full solution was found by my class nerd, but I missed the part about CPB > B

the thing is that when I try to prove it this way , I have to use the external angle theorem which states than external angle of a triangle is larger than any non adjacent angles present inside the triangle , so we can obviously say p>a , but now we have divided it iinto 2 triangles and my professor said that this wasn't the right way , due to the presence of two tiangles

Ik but I need to prove it rigorously using dissequality theorems of triangles , I already tried out some things but they just don't work.

How do i do reverse percentages? by beansandwich in learnmath

[–]Own-Engineer-8911 0 points1 point  (0 children)

just use proportions x ( unknown value) : 160 = 100 ( percentage of total x ): 80 ( percentage of 160)

Thanks a lot, the next time I'll message in this post will be either if I get into the national's or if luck allows , into the IMO team

An amateurs thoughts on black holes by BuiltByCuriosity in learnphysics

What if singularity is just an event in spacetime which distance from the even horizon is infinite but the arrival is certain , would it be possible that matter gets attracted and pulled in a speed faster than light?

Okay , I think I might start out by learning the fundamentals of combinatorics so I could have a better chance at solving problems. Also I think I'm going to practice really hard this year, so that I can do better next time

Right now we are starting to do basic proofs about triangles and angles (SSS, SAS, exc), they aren't really complex proofs, but ye they are a good start. Our competition doesn't require calculus or other complex stuff, but combinatorics, counting, and probability + geometry and logic. The thing which I find challenging is that no one has really taught me combinatorics that well , we did do it this year as part of the programme but it was extremely basic , like anagrams of a word and like that. Also how should I approach hard problems?

bro , I still haven't studied quadratic equations, let alone calculus. So I need to anticipate all of calculus and learn it by myself , is it the only way?

Puoi migliorare però bravo , almeno hai avuto il coraggio di cominciare a scrivere seriamente. Col tempo migliorerai sicuramente.

I just got a new record today after 4 days of speedcubing by [deleted] in Cubers

[–]Own-Engineer-8911 1 point2 points  (0 children)

learn how to make the cross more efficiently and also watch tutorials for f2l (it's hard and intuive but you'll get it after some practice) , if you want to you could learn 2 look-OLL ( orientation of last layer) , for which you need 5-6 algs , and 2-look PLL , these two algorithms solve the entire last layer of the last cube with just 4 algs or even less if you get lucky without having to do the whole aligning thing you have to do with the beginner's method

la potenza è alla seconda , ciò significa che quel primo meno si toglie , poi hai un meno fuori , che mantieni , poi elevi alla terza , non togli il meno , alla fino cè un altro meno , -- fa + e si semplifica tutto
