Find all solutions of the equation in the interval [0, 2π). (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
4 sec^2 x + 2 tan^2 x − 6 = 0
--------------
If there is no solution, enter NO SOLUTION.
These instructions are just an irritant. Do you think we can't say "no solution?" if appropriate?
