22*arcsin 45

NG is correct that   sin(45°)  =  $\frac{\sqrt{2}}{2}$

However,   arcsin(45)  ≠  $\frac{2}{\sqrt{2}}$

If     a  =  arcsin(45)     then     sin( a )  =  45

But there is no possible angle  a  that can make   sin( a )  =  45

The biggest possible value of  sin( a )  is  1 .

So there is no real answer to this.
