     30:60:90    ⇒ OE = (√3)
$$\: \\ $$$$\:\:\mathrm{30}:\mathrm{60}:\mathrm{90}\: \\ $$$$\:\Rightarrow\:{OE}\:=\:\sqrt{\mathrm{3}} \\ $$$$\: \\ $$

∠AOE=30  ∴ OA=2AE=2(1)=2  AE=(√((OA)^2 −(AE)^2 ))     x=(√(2^2 −1^2 )) =(√3)
$$\angle\mathrm{AOE}=\mathrm{30} \\ $$$$\therefore\:\mathrm{OA}=\mathrm{2AE}=\mathrm{2}\left(\mathrm{1}\right)=\mathrm{2} \\ $$$$\mathrm{AE}=\sqrt{\left(\mathrm{OA}\right)^{\mathrm{2}} −\left(\mathrm{AE}\right)^{\mathrm{2}} } \\ $$$$\:\:\:\mathrm{x}=\sqrt{\mathrm{2}^{\mathrm{2}} −\mathrm{1}^{\mathrm{2}} }\:=\sqrt{\mathrm{3}} \\ $$

x^3 −x=c
$${x}^{\mathrm{3}} −{x}={c} \\ $$
