Sir when we calculate rank and say I reduce the matrix to upper triangular matrix then the rank will always be n ? 0 votes 0 votes Lakshman Bhaiya commented Oct 24, 2018 reply Follow Share For a unique solution case, if $\lambda\neq5 $, is enough, it does not depend on the $\mu.$ for this case $\mu=9$ or $\mu\neq9$ it doesn't matter in case of a unique solution.Because when $\lambda\neq5$,rank of (A)=3 and rank(A:B) is also $3$. Rank=Maximum Number of independent Rows/Columns. Rank=Dimension(Order)-Nullity. 1 votes 1 votes Please log in or register to add a comment.
