the sum of eigen values of 2*2 matrix is trace(sum of diagonal elements) and the product is determinant . if you know this trick then you can solve one question in all entrances ...........

I am searching whether this trick is applicable to higher order matrices 3/3,4/4 etc...
If you know the answer please post it...

 

on calculating the determinant of higher order matrices the diagonalisation is useful

i don't know about eigen values,

if any one know please comment here.

 

Download speed of internet.....
I think the question is wrong..writing kbps is different from kBps...small b stands for bit and big B stands for byte .In home the speed of internet connection speed is specified in kbps.But when we download something using firefox,download manager or torrent download speed is specified in kBps..

 

I have written more then 5 questions from paper 2.. soon I will upload it.. thanx

 

Q.What is the role of heat sink in a computer system:-
a.cooling of memory chips
b.cooling of microprocessor

 

mass of a substance measured at madras,delhi ,madrid and iceland follows which order from the following options
a)madras=delhi<madrid<iceland

 

on dec net there is aquestion that what is the relation between coherence length and london penetration depth of type -2 superconductor

 

I am verifying that in square matrix of any order ,sum of eigen values is trace ,product is determinant
reference :grewal,higher engineering mathematics,40th edition,page 63.........
A SURE QUESTION FOR ALL ENTRANCES

 

verifying that in square matrix of any order ,sum of eigen values is trace ,product is determinant

it is a property of all equations like

a x^n + b x^(n-1) + d x^(n-2) ...............+(*) x + c

sum = -b/a
product c/a

for second order equation we can calculate the answer from our mind.

but in the case of n-th order equations the terms with d,e,f.... arising
i m trying to find a simple trick to find the solution....

 

Product is -c/a when degree is odd,+c/a when even.

in paper 2 one question of lagrangian n lagrangian equation was there..
another question was from particle physics n dat was a relation between strange,isospin,baryon no. was given n diff particles like ^,K...etc were given n their charges were to find...
in paper 2 particle physics was dominating
