I know this method already please solve it in the method asked.
In case of matrix we can't apply Ax=0 method
we apply this in Linear transformation
why can't we apply it in case of a matrix?
first of all Ax=0 denotes system of linear equations....when we put Ax=0 then we get solution of system of linear equation...not nulity of matrix
null space definition N = { x€V | T(x) =0 } applicable if mapping is defined
for matrix A result is rank(A) + nullity (A) = number of columns
