So I was trying to find the projection of the first quadrant of the unit circle onto the line 1-x. Is my reasoning/answer correct?

The problem I am trying to solve is to show that the suspension of the unit n-sphere is homeomorphic to the n+1-sphere, [math]\Sigma S^n\cong S^{n+1}[/math], where [math]\Sigma X = X\times[-1,1]/\sim[/math], where [math]\sim[/math] is the relation [math](x,-1)\sim(x',-1)[/math] and [math](x,1)\sim(x',-1)[/math].
