⇒−1<arcsinx<1 ⇒−(π/2)<x<(π/2)
$$\Rightarrow−\mathrm{1}<\mathrm{arcsinx}<\mathrm{1}\:\Rightarrow−\frac{\pi}{\mathrm{2}}<\mathrm{x}<\frac{\pi}{\mathrm{2}} \\ $$

 x = ((π −(1/2))/2)  ⇒ arc sin(((π−(1/2))/2)>1)=?
$$\:{x}\:=\:\frac{\pi\:−\frac{\mathrm{1}}{\mathrm{2}}}{\mathrm{2}}\:\:\Rightarrow\:{arc}\:{sin}\left(\frac{\pi−\frac{\mathrm{1}}{\mathrm{2}}}{\mathrm{2}}>\mathrm{1}\right)=? \\ $$
