What is the output of the following code?

$x=$linspace$(-2*,2*,400)$;

$y1=sin(x)$;

$y2=cos(x)$;

$y3=sin(x){*}^{**}cos(x)$;

figure;

plot$($x$,$ y$1,\text{'}$r$--\text{'},$ 'LineWidth', $2)$;

hold on;

plot$($x$,y2,{?}^{1}b$:${?}^1,$ 'LineWidth', $2)$;

plot$($x$,$ y$3,\text{'}$g$-\text{'},$ 'LineWidth', $2)$;

hold off;
