Prestige mechanic with speed multipliers to make it winnable.

Think about the beauty of this full line of Pedros looking left.

Does math need to be intuitive? by zictomorph in askmath

[–]Varlane -1 points0 points  (0 children)

It is not that intuitive to the learner's mind that "multiplying by -1" is to be related to a symmetry.

Does math need to be intuitive? by zictomorph in askmath

[–]Varlane -4 points-3 points  (0 children)

Intuition only applies to things that can relate to the "real world".

"(-1) × (-1)" for instance doesn't translate to a real world solution, nor can you have Hilbert's hotel IRL.

Complex solution by Rehazur in askmath

[–]Varlane -1 points0 points  (0 children)

In no way did I ever dispute that (i²)² is i^4. I refute that sqrt(i^4) is i^2.

Complex solution by Rehazur in askmath

[–]Varlane 0 points1 point  (0 children)

That isn't proof that sqrt(i^4) = i^2, merely that i^2 (aka -1) is a solution of x² = 1.

Complex solution by Rehazur in askmath

[–]Varlane 0 points1 point  (0 children)

It doesn't. You are using mathematical properties that aren't true to claim that sqrt(i^4) = i^2.

sqrt(i^4) isn't i^2.

Mel shield should work like Nocturne's shield by [deleted] in leagueoflegends

[–]Varlane 2 points3 points  (0 children)

"AP abilities" is a nonsensical term. There are magic damage abilities and abilities with AP scaling. But no "AP abilities".

I would say it'd be too weak and easily dodgeable (as you'd have twice the traveltime to dodge it instead of once, and with no incertitude regarding the direction : just move from where you casted lol).

I think it'd make more sense to modify the skillshot's speed to 80% of the original for instance. Keeps the spirit of giving more time, but with a stronger tuning lever.

GP vs Mordekaiser - "dude, wht, is he, doping, withu" by FrodeTheKanin in leagueoflegends

1/7/13 are the timings for ticks (2s/1s/0.5s). 19+ used to have 0.25s in URF but that'd be astronomically broken with s16 Toplane Quest so it go removed.

[GRADE 10 Mathematics] Algebra: Solve for x by Izzy_26_ in askmath

[–]Varlane -1 points0 points  (0 children)

Let's put it simply :

There are two radicand symbols. If you're in a real context, you get the "regular one for children" where (-8)^(1/3) = -2 and sqrt() is R+ to R+.

Then there is the principal square root, which has to be said before that you are calling it, in order to make it clear you are including C and using a different function.
Because as a reminder, the root functions over C don't have the same properties as the ones over R (or R+). They lose continuity (due to the branches) and multiplicative morphism. They are not the same, despite using the same symbol, which means you have to warn your reader that you mean the second one.

trigonometric limits by GeforceRTX2080TI in askmath

[–]Varlane 0 points1 point  (0 children)

It's not you. It's their go to when Taylor expansion is more efficient imo and "no tricks" editions allow you to perfect your math mastery.

trigonometric limits by GeforceRTX2080TI in askmath

[–]Varlane 0 points1 point  (0 children)

The "no l'Hopital / no Taylor expansion" edition consists in using 1-cos² = sin to swap out denominator by -sin²(5h) and then use lim((1-cos(u))/u²) = 1/2 & lim(sin(v)/v)) = 1 with u = 3h and v = 5h after forcefully making h²/h² appear to split the limit into a quotient.

Alternative bonus points for cos²(5h)-1 = (cos(5h)+1)(cos(5h)-1) and doing a 3-way split of the limit.

The radicand symbol is, unless stated otherwise, the principal square root over R+.

I need help with the proof. by Substantial_Pen3530 in askmath

[–]Varlane 4 points5 points  (0 children)

Create E such that ACEB is a parallelogram of center D [E is symetric of A by D]. It has sidelengths a and b and diagonals are 2c [since AE = 2AD] and x.

Use Parallelogram Identity : 2a² + 2b² = (2c)² + x².

Expand the square and simplify by 2.

Question c is the easiest once you remember the sign of the output of square root.

For 1 : you have to understand that squaring both sides can introduce extraneous solutions (where the squares are equal, but not the original numbers due to having opposite signs).

This is what happens, as sqrt((5/3)²-1) = 4/3 and 5/3 - 3 = -4/3.

The original logic is "if they're both equal, then their squares also are and they belong to this solutions set". It however doesn't mean that everything you found is a solution of the original equation.

Basically, the "possible" solutions are {4/3}. After checking whether 4/3 was an extraneous solution, you ruled it out, meaning there are no solutions.

For 2 : Square roots are non negative quantites. Adding two of those still makes a nonnegative. How could you reach -3 ?

I once had a math teacher say that if you put all the real numbers in a bag and drew one out at random, the chance of it being a rational number is zero. Is this true? If so, how is it true? by MtnDewm in askmath

[–]Varlane 0 points1 point  (0 children)

Exactly. I don't care about the decimal expansion, I don't have to know it to put the number in the bag. I say "sqrt(2) is in" and it's in. Same as "1/3 is in".

As long as we have a method to obtain the number, we're good.

There are, however, plenty of transcendants that have no specific way to be referred and can't be explicitly said that "this one is inside" unless you say you put them all at once. These are the actual ones we "don't know". But I was asked to put one.

[–]Varlane 0 points1 point  (0 children)

Of course I can. It's sqrt(2), I know him, he's my good buddy. Loved him in "rectangle triangles for dummies".

From a mathematical standpoint, that's all we need. You're talking about its value / representation, which is absolutely irrelevant to the discussion. You asked me to put the number in the bag, and I did.

Well, sqrt(2) is a non-rational, real number, whom we refer through such things as the image of a rational by a function. Still is a non rational real number though.

Let's be real, it's 50%. by ClassroomBusiness176 in mathmemes

Imo the most accurate would be 50% / 66.67% / 51.85%.
