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, if needed, 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.
sin x=-1/2 |dw:1408306159725:dw|
2 cos x=√3 cos x=√3/2|dw:1408306308763:dw|
