Question:Solve trig equation in specified domain

Why is it that maple produces an incorrect answer in this command:

`assuming`([RealDomain[solve](sec(x) = sqrt(2), {x}, useassumptions)], [x > 3*Pi*(1/2) and x < 2*Pi])

 

and no answers in this command:

RealDomain[solve]({x > 3*Pi*(1/2), sec(x) = sqrt(2), x < 2*Pi}, {x})

 

???  Please help???
