I know you may not believe the things I'm going to say, but I assure you they are all true. As of lately I've basically stopped playing video games. Not willingly. This was a process that took years of slowly declining interest. I guess I'm just growing up. I figure I might as well give away these games to someone else to enjoy them. The catch is you have to solve this problem. It is admittedly challenging, but I solved it in 10th grade after learning Calculus 2 and I've seen 2 other proofs by professors since.

A bear starts on the [math] y [/math] axis at [math] b [/math]. A man starts at the origin. At [math] t=0 [/math] the man runs right along the [math] x [/math] axis at a constant speed [math] S_m [/math]. The bear chases the man by always running directly towards the mans current location at constant speed [math] S_b [/math]. We are given [math] S_b > S_m [/math]. The bear will always catch the man eventually.

In terms of [math] S_b, S_m [/math] and [math] b [/math] what is the length of the bears path from its starting position to where it catches the man?

This problem is stupid. Its a nonlinear ODE with well posed initial conditions. Pretty sure the solution is of constant derivative as well.

Just find where the bear's near trajectory crosses x.

Don't give anyone your games OP. This shit is too simple.

Not that guy, but there's nothing in ToS saying you're not allowed to play TF2.

GIFs like these are criminal, do you know why?

They cruelly give the perceptive taste of being in that enviroment, witnessing such 'natural' beauty and then you are forced unto the harsh reality that this is nought by the rendering of someones imagination and that such an event or place will never be visitable by you in the material.

This is why it is criminal, because it raises and dashes your hopes for aesthetic perfection within the same time frame is takes you to appreciate it.

I can't argue against such a refreshing opinion, but do painters paint in order to try and capture external beauty or because the paintings alone are beautiful?

>> No.8828083

>>8828066
Both.

For instance, the abstract artist may paint an abstract canvas that has no tangible meaning, but may have symbolic meaning.

Whereas a realist, may paint a canvas to capture the raw imagery of scene without the need for 'meaning'.

So I would say that is is entirely subjective and dependant upon the intent of the artist, as it cannot be argued that it is tied to ideology, philosophy or even artistic movement as a surrealist is as able to capture natural beauty , as a Pre-Raphaelite is.

I'll restate it

My question was whether an artist paints a painting in an attempt to capture external beauty or because the painting in itself is beautiful.

I figured you had read the question which was enough for me. Sometimes its nice to appreciate opinions without thinking too deeply into them.

I'm not a lawyer. I don't know how much information steam needs before it can close down an account. But everyone is giving me a hard time when they don't know this either!

I don't care if it gets shut down at this point because obviously no one wants it. I just thought it'd be better off in someone else's hands.

I decided to give it a try, but I'm not expecting to get anywhere anytime soon—highest math I took was calc 1 before deciding to become a professional diver. I'm not amazing at writing proofs so even if I get it I won't post, but thanks for giving me something to refresh on.

The answer is [math]\frac{b}{1-\frac{S_m^2}{S_b^2}}[/math]. Since you "have already solved this before" you surely know how to arrive at this result.

C=(b+( ∞ Σ i=0 (m+xSm:b-root(Sb^2-m+xSm:b-y)))*[pi]*((1+3λ^2):(10+root(4-3λ^2))):4

y=m+xSm:b-root(Sb^2-m+xSm:b-y

You're the one who supposedly wants to get rid of his steam account. I'm not going to bother writing the proof in a legible fashion before you send me the login details.
In broad terms, the answer can be obtained by parametrizing the path by the y coordinate and obtaining the time from the arc length of the curve (as an integral). The resulting differential equation can be solved exactly with the correct ansatz.
