| I'm looking to solve the equation
|  (13 Cos[q]-(5+8 Cos[f]))^2+(13 Sin[q]-(7+8 
|  so that I can graph phi as a function of theta 
in the first quadrant only. A 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.?
