# Find $$y$$?

Calculus Level 3

$\lim_{x\to0 } \left [\left \lfloor \dfrac {\sin x}x \right \rfloor + \left \lfloor \dfrac x{\sin x} \right \rfloor + \left \lfloor \dfrac {\tan x}x \right \rfloor + \left \lfloor \dfrac x {\tan x} \right \rfloor + \lfloor \cos x \rfloor \right] = y + \dfrac1y$

Find the value of $$y$$ satisfying the equation above.

Notation: $$\lfloor \cdot \rfloor$$ denotes the floor function.
