Hello, In my opinion (it's not the field I prefer), there is a problem : Originally Posted by ginafara so here, because from r(a)=0, you state that Plus, if you go this way, you can directly say that since it's the null function ~
i think you are actually done but you missed some reasons. note that or , that is but the case cannot happen otherwise is a constant and that . thus , that is is a constant function. but you have shown that and therefore .
