Your equation can be written as
1 cos 2 ( x ) =
1 + tan 2 ( x ) = 2 3 tan ( x ) 2
or
tan 2 ( x ) 2 3 tan ( x ) + 3 = 0
the reduced discriminant is
δ = 3 3 = 0
thus, there is one solution given by
tan ( x ) = 3 which gives
x = π 3 .

Why is tanθ1π2θ for θ close to π2?
I wanted to see what the behaviour of the steep part of the tan curve was like, i.e. the behaviour of tan(x) as x(π2). So by thinking about a shift of the graph of tan(x) byπ2 to the left, I put some small (positive and negative) values of θ into my calculator for the function tan(θ+π2)
tanθ1π2θ for θ close to π2?
or, in more colloquial terms,
The steep part of tanx is just like the steep part of 1x
But why is this the case? I couldn't deduce it easily using the Maclaurin expansion of tan(x). Is there a more intuitive explanation? I couldn't think of any explanations analogous to those explaining small angle approximations.
