comment Fitting a function
You could use a rule fit /. m_ t + c_ :> m or pick out the right part fit[[2, 1]]

comment Too much whitespace in a GraphicsGrid containing Legended Plots
You could try Grid instead of GraphicsGrid.

comment Newton-Raphson Method and the Van der Waal Equation Coding question
Looks like you actually want a root this time instead of the minimum. Change FindMinimum back to FindRoot. Also don't forget to adjust your PlotRange.

comment Newton-Raphson Method and the Van der Waal Equation Coding question
Starting conditions were found by trial and error: minimise with a starting value function, plot the results, make up a new function that approximates the good bits of the plot, repeat. See the edit for a better way to do it.

comment Customizing & finding intersection points in polar plot
That's why I'd like to know exactly what the theorem is. As far as I can tell, the curve does not go through equally spaced points at those angles (aside from my ability to count to eight).

That's not a golden spiral. This might be PolarPlot[GoldenRatio^(2 n/\[Pi]), {n, 0, 2 \[Pi]}]. Can you quote or link to the theorem?

And should x0 be -50 or 10^-50?

What's x2? Also, your function f doesn't seem to use xe?
