Question

A is a square matrix of order n.
l=maximum number of distinct enteries if A is a triangular matrix.
m=maximum number of distinct enteries if A is a diagonal matrix.
p=minimum number of zeroes if A is a triangular matrix.
if l+5=p+2m , find the order of the matrix.

Answer 1

find I and P in the same side

Answer 2

sorry...didnt understnd..

Answer 3

L and P will give you the number of entries in a square matrix.

Answer 4

ohkeyy yes...den??
vatz the answer??

Answer 5

squareoot that value

Answer 6

bt how we will find l and p??

Answer 7

Isolating m then plugging it in to the original

Answer 8

solve and show pls..

Answer 9

Take an arbitary matrix (a 2x2) and try to figure it out.

Answer 10

Like for a matrix that is 2x2 the most
in this case it will be m=2, p=1

Answer 11

yeah...bt we dnt noe the order..that is what we hv to find..

Answer 12

well keep doing it until you find it. I know it's not a 2x2 because the right side will be 5 and that means l has to be 0 and thats not true because l=3

Answer 13

well the way i think it...it shud be l=m+p...
putting this in the givn equation will give the result m=5
bt the order givn in answer is 4...

Answer 14

I get 5 too. :/

Answer 15

5 here also

Answer 16

bt answer vd me is 4 :/

Answer 17

sometimes book is wrong, :)

Answer 18

hmm...so 5 final??

Answer 19

would be my choice

Answer 20

so will be my....thank you!!

Answer 21

Well that's the most it can have but I guess it can be anything bellow 5 order.

Answer 22

In that case how will the equation b satisfied...??

Answer 23

It say maximum distinct. Which means the largest matrix you can form. Doesn't restrict yo in using just 1 dinsinct diagonal

Answer 24

o yeah...u right..:)

Answer 25

my head hurts so probably someone else can write it a better way.

Answer 26

vat does dat mean??
