Is mathematics a discovered (natural) or man-made phenomena?
Personally I think it's natural because it can precisely describe natural events and laws which those events must conform to.
Thoughts on this?

It's both natural and man-made. Look at that documentary where Zizek is standing in a pile of garbage, and saying, "This is the most natural thing in the world!". Nature is man. Culture is nature. Man is not separate from nature. You can't take biology out of the environment from which the gene evolves.Well, you hear "Time/space/maths doesn't exist, man" so often. But for whom does it not exist?I perceive its existence. How do I perceive it? Through my nervous system. My nervous system is receiving billions of signals every second.Luckily there is a brain there which categorizes those signals for me into distinct tracks based on what has been evolutionary fit. That way, when I see a bear in the forest, I don't take out my ruler and try to measure every hair on his body in order to determine if the bear is a threat. Automatically my brain detects a threat and different glands fire off hormones, etc. and I find some way to keep my pic-a-nick basket.To get a real answer to this, you have to look at the nervous systems evolved through time, and how nervous systems react to the phenomenal world. We still have amoeba, reptile, mammal, etc. sense, and that affects our perception. The 'tracks' where we store imprints about previous threats/comforts determines our perception.Euclidean geometry is only an explanation of the world as it relates to the perception of domesticated primates. We wouldn't see space in 3D if our nervous systems were different. We wouldn't plot points in 3D space if our nervous systems were different. Phenomenal existence only appears as it does because we evolved through all of the other species in the environment and atmosphere that we did.tl;dr perception is everything, practice magick and cast spells dude

Euclidean geometry may be somehow favored'' by our biology because it is a good local approximation of the acutal curved space in which we live, but even if a creature evolved in a truly alien geomtery it would still make up the geometry we live in if it was intelligent, just like how we have made up infinite families of alien geometries that don't obviously correspond to our physical reality.

Here you're just multiplying the top and bottom of the fraction by 2^5*7^2. The 2^5s cancel in the top and the 7^2 cancel in the bottom.

So I'm working on a Calc II assignment, and I'm stuck on a problem that asks for the volume of the infinitely long solid attached.

f(x) = xe^(-x^3), so I can prove that the integral converges. I'm a lazy cunt so I used Wolfram Alpha to evaluate the integral and the answer involves the gamma function, which puts solving it beyond the level of this class.

So is there a more obvious way to go about this problem, or did my prof. assign a problem that we can't actually do at this level?

Ok so long story short - my math teacher this semester is the wort teacher ive ever had in my entire life. Asked him what formula they used to cme up with the xy coordinates on a unit circle. Example: terminal leg of 45* aka pi/4 on the unit circle intercepts at p=(root2/2, root2/2). He said there is no formula you just have to memorize. Are you kidding me i studied the chapter over and over and realized its the pythagorean theorum no matter what the radius equals. What a shit teacher.

Anyway my question is how does sin=y, but the fundamental idenitity of sin is 1/csc? Does this mean that y=1/csc?
Part 2: can that one be interchanged with any value of r? For example does it apply for circles that are not unit circles?

I know this is super basic, and my book explains it in a complex way, but its not like i have a good enough teacher to ask any questions to fill in the holes. Ive had straight a's and b's in my previous classes up til this guy.

So your problem is basically that you are in middle or high school and no one has ever taught you what a function is. Related problems include not knowing anything about set theory and having a poor grasp of English. I'm sorry but the education system sucks.A set is a collection of things. For example, the collection containing the numbers 1, 2, and 4 is a set, which we write {1,2,4}. Sets can have anything in them, and can even be infinite, like the set of all polygons or the set of all rational numbers (fractions).Anyway, a function from a set, say A, to another set, say B, is a correspondence which sends each thing from A to some thing in B. For example, if A is the set {1,2,3} and B is the set {4,5,6}, then we can define a function, call it f, where f(1)=4, f(2)=5, and f(3)=4.The sine function is a function which maps real numbers to real numbers. Unfortunately it will be a very long time until you are ready to understand what a real number is, but the people in charge of teaching you are fucked beyond belief so this can't be helped.Since the real numbers are an infnite set, we can't write down the sine function by saying what each real number gets sent to. That is, we can't write out sin(0), sin(1/32), sin(pi), ... and ever get done saying what sine is. We need a rule to define the sine function so that we know what it is we are talking about. (Knowing what you are talking about is something that most people neglect, but in math it is very important.) This rule is the one you deduced correctly even when fed garbage information. Given some real number t, the value of the sine function at t, which we write as sin(t), is defined to be the y coordinate of the point on the unit circle which intersects the line which makes angle t with the x axis. You can find videos and pictures describing this.There is a formula for the values of the sine function in terms of addition and multiplication, but it is infinitely long and thus beyond you. The geometric definition will have to do for now.There is another function called the cosecant function which is defined by the rule which sends t to 1/sin(t). That is the definition of csc.I hope this helps.

Ok, so how would you introduce someone to the fun bits of mathematics? My girlfriend has maths at standard grade (8/9th grade for Americans I think), and she's interested in seeing why I do it just for fun. She isn't too patient with it, I tried to explain that x^1/3 is the cube root of x and she just got angry after a while and quit, so it needs to have the most 'wow' for the least amount of difficulty (basically math porn). I was going to show her some very basic calculus and some quadratic equation shit, but I'm doubting myself now.
What should I be showing her, or is it a lost cause?

I have the same problem. I can't seem to be all that interested in mathematics. The only thing that serves as a motivation is when I solve a problem, which I see as moderate to hard, by myself. Too bad I am bad at maths, so that dopamine release doesn't happen a lot. I see the proposal of mixing maths with something you find genuinely interesting being mentioned. The only thing is, I find everything from astronomy and botany to politics and art interesting. I do not have many hobbies, because I usually lose interest in them after a period. I have brewed, planted, and written graffiti, but they never stick for more than a few projects.How do I get myself interested in the amazing world of mathematics? I really want to be able to do complex equations one day. Is it really nothing else than forcing myself to do a few problems every day? I have the attention span of a pornstar's pubic hair, so I don't think that will work for me.

it's a great way to see the impact of changes in your model. Of course this applies mostly to folks interested in applied mathematics. But what is "pure" mathematics, but math that hasn't been yet applied? Give me a physical interpretation of the fractional calculus. Better yet, show me it in a Game.

There's also the fact that a lot of gamedevs struggle with some basic maths, mostly stuff regarding linalg, quaternions come up a lot. You could probably help!

Did you know: There's a 420chan amateur gamedev community, >>>/vg/664016

And from a pedagogical pov, who'd bet against gamedev working its way into the classroom? It's the perfect confluence of any applied area you can think of, Fourier series to taxicab metric

My first program was a game and later gamedev had me apply trig. It is still a lot of boring work, too, a lot of pure programming, so to speak, as pure maths is applied to maths.Planning is required when fleshing out an game from scratch. There could be too much freedom in a project to grade it. Gamification works better if fit to the audience, eg. in a logic puzzle game.

How do I recover the signs of integrals and derivatives? by Nell Penderfedging - Sun, 15 May 2016 20:44:52 EST ID:1eeqYqTy

I can define derivatives and integrals in terms of the Lebesgue
measure but how do I recover signs?

$$\left. \left\lvert \frac{\mathrm{d} y}{\mathrm{d} x} \right\rvert \right\rvert_{x = a}= \lim_{C \rightarrow \left\{a\right\}}\frac{\lambda^*\left( \left\{ y_x \, \vert \, x \in C \right\} \right)}{\lambda^*\left( C \right)}$$

$$\left\lvert \, \underset{\, \, x \in C}{\int} y \, \mathrm{d} x \right\rvert = \lambda^* \left( \left\{ \left( x , y_x \right) \, \vert \, x \in C \right\} \right)$$

The first is to define the integral in terms of the lebesgue measure and use the doublet distribution to define the derivative in terms of an integral transform and the second is to define a delta as the lebesgue measure of the increasing sections of a function minus the measure of the decreasing sections of a function and then define the derivative using the delta as normal.
