It's actually a good question

>>8808927
Each has 2 in denominator and 1 in numerator. Unsolvable.

Put 1000 for banana and 1 for tomato and pineapple. It is greater than 4. Put 1 for banana, tomato, and pineapple. It is less than 4. Because the rate of change between the two is continuous it must have a solution(s)

[eqn] a = e(b+c),\ \ b=f(c+a),\ \ c=g(a+b) [/eqn]

[eqn] b=fc + feb +fec \implies b=cf\frac{1+e}{1-fe} [/eqn]
[eqn] a = c\big(e +e\frac{f+fe}{1-fe}) = ce\frac{1+f}{1-fe}[/eqn]

I studied this shit extensively through the playing of kerbal space program.

Basically, delta v is "change in v", aka, "change in velocity.

When you're in a vacuum of space, accelerating in a certain direction will change your course in a certain way. It's basically a way of describing how much your fuel is able to make you move, being a function of ISP (miles per gallon) and the amount of fuel you bring.

There isn't just one correct answer. If you multiply Apple, Banana and Pineapple by the same number, you'll get the same result.

So, I believe the answer is:
Apple = Real number greater than 0
Banana ≈ Apple * 3.732
Pineapple = 0

This problem has multiple solutions. Here is one such solution in paragraph form.

If one fruit (say pineapple) equals 0, then...
another fruit (say apple) equals 2±√3, then...
the last fruit (in this case banana) can be any number.

One example of a valid answer:
pineapple = 0
apple = 2±√3

> Can you find values for apple, banana, and pineapple?

The answer is yes, you can find values for them that make the equation true.

The question doesn't ask for an example of these values, but if you're interested, one such triple is:

apple=0
banana=1
pineapple=3.732050807568877

(The pineapple is the larger of the two solutions to the quadratic equation p^2 - 4p + 1 = 0.)

>>8815491
The idea of composition in the fundamental group is that of traveling the first path and the second in succession, or, equivalently, setting their two domains together. The concept of composition that we want for the n-th homotopy group is the same, except that now the domains that we stick together are cubes, and we must glue them along a face. We therefore define the sum of maps f, g : [0,1]n → X by the formula (f + g)(t1, t2, ... tn) = f(2t1, t2, ... tn) for t1 in [0,1/2] and (f + g)(t1, t2, ... tn) = g(2t1 − 1, t2, ... tn) for t1 in [1/2,1]. For the corresponding definition in terms of spheres, define the sum f + g of maps f, g : Sn → X to be Ψ composed with h, where Ψ is the map from Sn to the wedge sum of two n-spheres that collapses the equator and h is the map from the wedge sum of two n-spheres to X that is defined to be f on the first sphere and g on the second.

If n ≥ 2, then πn is abelian. (For a proof of this, note that in two dimensions or greater, two homotopies can be "rotated" around each other. See Eckmann–Hilton argument). Further, similar to the fundamental group, for a path connected space any two basepoint choices gives rise to isomorphic πn (see Allen Hatcher#Books section 4.1).

It is tempting to try to simplify the definition of homotopy groups by omitting the base points, but this does not usually work for spaces that are not simply connected, even for path connected spaces. The set of homotopy classes of maps from a sphere to a path connected space is not the homotopy group, but is essentially the set of orbits of the fundamental group on the homotopy group, and in general has no natural group structure.

A way out of these difficulties has been found by defining higher homotopy groupoids of filtered spaces and of n-cubes of spaces. These are related to relative homotopy groups and to n-adic homotopy groups respectively. A higher homotopy van Kampen theorem then enables one to derive.

How are effects produced as queer across interwoven spaces?

Maybe you should change "aether" for "solar X" (solar powered, solar panels, solar cells, ..) even if it's a bit too easy, i think "aether" is too tricky to score.

what's this from

>>8810262
it says that since the two things are touching, the distance between their mass is 0

and therefore the gravitational force between them is infinite.

which is wrong, therefore gravity doesn't exist

In general, when you assume one of the variables is 0, you can compute the other 2 with 0.5 = sin(2*t), then, use t on x = r*cos(t), and y=r*cos(t), where r is any non-zero real number.
