Trig 30
x/2 = 2pi/3 yields a unique solution of x = 4pi/3 Does this answer come from some trig equation? Your subject title suggests that. In that case find the period of the trig function, then add k(period) to 4pi/3, k an integer.

Subtract 2 pi from 7pi/3. The trig functions of 7 pi/3 will be the same values as the trig functions of pi/3, which is 60 degrees. The cosine of pi/3 is 1/2. That makes the secant 3. The tangent is sqrt3 You should be able to look up or figure out the other funtions of that ...
