(a) Use Mathematica to find an echelon form of A.
(b) Using your answer to the previous part, find the rank and nullity of A.
(c) Find a basis for the row space of A.
(d) Find a basis for the column space of A.
(e) Find a basis for the null space of A.
(a) solution: reduced row space echelon form of A
(b) rank
nullity:
rankA + nullityA = number of columns of A.
therefore, nullityA= no. of columnsA - rankA = 5-3 =2
(c) row space of A
(d) column space of A
(e) null space of A
