Trigonometric Equations:
Solve each of the equations for 0≤x≤2π. Isolate the variable, sketch a reference triangle, find all the solutions within the given domain, 0≤x≤2π. Remember to double the domain when solving for a double angle. Use trig identities to rewrite the trig functions.

sin x=-1/2 2 cos x=√3

4 cos² x-3=0 sin² x=1/2

Help with any of these would be greatly appreciated...
