C[1] is the first arbitrary constant (highlight C and select from the menu
Help/Find Selected Function.../
Do the same for && and other unknown operators.
Your equation was somewhat garbled. Try something like this
Needs["Graphics`"];
ImplicitPlot[(13 Cos[q]-(5+8 Cos[f]))^2+
(13 Sin[q]-(7+8 Sin[f]))^2==49,
{q,0,4Pi},{f,0,4Pi},PlotPoints->100];

graph of the solution obtained using the Solve command produces
unexpected results and I haven't used Mathematica much so I'm having
trouble intrepreting the results that the Reduce operation produces. I
understand that the solution is periodic but can someone interpret what the
other symbols in the solution mean, e.g., C[1], &&, || etc.?
