It is not quite clear what you really want. A related problem can be found here [Basins of attracton]()

comment How to represent one variable in terms of others in a system of equations?
It doesn't make sense, 3 equations and more than 10 unknowns, moreover the first equation is just solved with respect to V0 and it doesn't appear anywhere else to be simplified more.

Are you sure Ctrl+Enter should work, shouldn't it be Shift+Enter?

comment Riemann Zeta function definition was expanded by Euler with an infinite product series
Take a look at this answer. Compare e.g. Product[1/(1 - Prime[i]^-4), {i, Infinity}]//N and Product[1/(1 - Prime[i]^-4), {i, 7}] // N, i.e. only the first 7 primes give a very good approximation. More on this topic can be found here Double series over primes.

comment Simplify Class invariant $G(25)$
Try e.g. TrueQ[G[25] == N[GoldenRatio + 1/10^14]]. Even though you get true it doesn't answer the question.

comment Finding Euler spiral convergence point for powers other than 2
@Mike'Pomax'Kamermans Your graphs are slightly puzzling. I've made quite nice plots but I will be able to add them in a few days, because my version of Mathematica (10.1) involves some internal problems when exporting graphics.

comment Finding Euler spiral convergence point for powers other than 2
@Mike'Pomax'Kamermans There is a general consensus on mathematica.stackexchange that whathever code one writes, it should be in a copyable form. As you may have seen the code written in latex cannot be easily copied. On the other hand in the Front End traditional notation is equivalent to the input form (with many restrictions though). So my intervention should be welcome, nevertheless you can edit your question to its initial form. However, I recommend to edit your question adding the code you have used to plot graphs.
