(f) there is a 0 such that u @ 0 = u for any u e V; (g) for any u E V, there is a - u E V such that u e (-u) =0; (h) 1 . u = u. (Hint: NOTATION MATTERS.) 2. An MA351 class in Fall 2021 is asked to solve a system of linear equation. Suppose the "left-half" of the class gives an answer as: while the "right-half" of the class gives: where $1, $2, t1 and t2 are all free variables. (a) Show that both answers are the same. (b) Express the following expressions from the "left" ( :)- (3 ) - (:). ( :)- (8)- (:). using the "right" form. (c) Express the following expressions from the "right" using the "left" form. For example, ( : ) - (8)- (:)-(8) (90)
