Instead of looking at q1 == q2 you might try to try and reduce q1 - q2 say by
Simplify[q1-q2] or Expand[q1-q2, Trig -> True] (*Trig->True for Trig functions*) Together[q1-q2, Trig -> True]
and combinations of these.
If you get 0 you have proved equality. If you can find numerical values for the variables and constants that definitely give a non-zero value then you will have proved inequality. And if a range of random assignments of numerical values all give 0 for q1-q2 it is probable that q1=q2.
