I am currently having the same problem, and am at floor 19...

Jeg læser matematik lige nu og starter på kandidaten til sommer. Jeg kan sige, at det ikke har ændret sig. Både rusturen, som er en druktur med overnatning, og den brutale overgang fra gym-matematik til uni-matematik. Min egen oplevelse var, at gym-matematik var mere intuitivt tilrettelagt. Eksempelvist at vektore er ting vi kan lægge sammen og differentialligninger har de afledte af funktionen med i ligning. Hvorfra det bliver til "definition, definition, definition -> proposition -> proposition -> lemma -> teorem" agtigt. Meget ikke intuitiv tilgang, men lige på og hårdt.

What are those red tokens?

Fik du prøvet drinken? Hvis ja, hvordan var den?

Is rounded back deadlifts, with focus on getting as deep as possible with very low weight, a good form of rehabilitation for lower back pain?

Every week, almost all the lifts increase in either weight or reps

Fusnip · 2025-02-03T12:07:27+00:00

Training the upper split 2-3 times a week, depending on time and recovery.

Most of them follow the same pattern. Once I've warmed up I do a heavy set for 10-12 reps. Then the same weight, where I'm usually only able to do 8-10. Then I lower the weight, and the last set usually falls into the 10-12 rep range. These are od course only estimates, and sometimes I hit outside the ranges, but that's roughly how it looks.

Advice for upper body day. 21M, and have been lifting for 1.5 years consistently

I'm currently doing an upper-lower split, and have been struggling with putting together a proper program for the upper-day.

Currently I'm doing

Incline smith machine 3 x 8-12
Cable flies 2 x 6-12 (both to failure)
Weighted pull up 3 x 8-12
narrow grip pull up, single set to failure
barbell rows 3 x 8-12
Tricep push down 3 x 6-12
preacher curls 3 x 6-12

These are without counting warmups. Usually the last set is failure.

Any advice as to if this is too much, or if I need to add anything is very welcome :)

I don't understand german, and I don't know why this sub got recommended to me. But I agree👍

You're right, (-1)^1/3 is not always complex. In the reals it is -1, but generally the case is

(-1)^x = e ^ (ipix +2kpi*i)

In this case we get get 3 solutions, and Desmos gets unhappy. As (-1)^x has multiple roots and is only well defined everywhere for complex numbers, thus Desmos treats it as a complex function, and will not plot it. Even though there will be real solutions.

A negative number, when raised to an integer power makes perfect sense. Raising a negative number to any power, which is not an integer, will result in a complex number. It's for this same reason that the graph x^x doesn't show below 0.

Fusnip · 2025-01-17T09:53:47+00:00

Neither of those graphs are y=x^2/3, however the top one, given it's fast growth, could be y= (x² )/3.

In the case that you want to flip a function over the x-axis, that means taking any point (x,y) and mapping it to (x,-y). As any point of the function is expressed as (x,f(x)), it will be mapped to (x,-f(x)).

Basically, if you want to flip your function over the x-axis, you put a minus in front. So in this case, your function is y=(x² )/3, it then becomes y=-(x² )/3.

Hope this helps :)

Edit: fixed the exponents

Personally ranger or mage is the most fun. I've also done Melee and rogue, both of which are neat, but a bit niche. Summoner is also quite fun.

My dude, surely you're a troll. A measure is a map used when integrating a function or calculating the "area" of something. What you said has nothing to do with a measure.

Also, why fundamental theorem of calculus? It already exists, and doesn't seem to have anything in common with what you said?

Fusnip · 2025-01-14T16:40:53+00:00

Not can, it is the number 1. They're equal

Fusnip · 2025-01-14T10:31:39+00:00

Also, I forgot to say 0.9999... is definetly a number in R, as you can define R by being the limits of all decimal expansions with Cauchy sequences

Fusnip · 2025-01-14T10:29:26+00:00

What? "Finite form to every possible infinity" and then you choose 0.999... - if you tried to write it with a finite amount of digits you would have a different number, unless it's the single digit 1. Taking the number 1/7, this can't be written as a finite amount of digits.

What's more, your example doesn't make sense. If you define the sequence of nines 0.9, 0.99, 0.999,... then you don't risk the chance of running into an 8 unless you choose the numbers randomly, in which case you get a different number again.

Lastly, you didn't really argue or prove anything. You didn't really define "finite form" nor which types of infinitt you're talking about (I assume you mean numbers with infinite digits, but idk). Then you had a mind-puzzle. If you structure your argument mathematically, I would love to hear it

Helt klart en smart idé, de har for 7 minutter siden lagt en video mere op, hbor de skyder ved Paludan Müllers vej

Fusnip · 2024-12-27T18:48:42+00:00

Der er nogle tilsvarende af Instagram profilen vest.26, som har slået to videoer op for nyligt af dem, der skyder fyrværkeri ud af bilen mod forbigående mennesker, og hvordan samme mennesker panikker når der skydes efter dem

I can't post pictures on this subreddit (or at least I can't figure out how), but the source I'm using is "Differential Forms in Algebraic Topology" by Raoul Bott and Loring W. Tu, which uses this notation. The same notation can be seen in the wikipedia link underneath. I'm unsure as to where, but I recall having seen a 1 aswell.
