multiplied 1st row by 2 and add to second row, multiply 1st row by 2 and add to 3rd row... dw:1334524445998:dw

so now i have these equations v1+v2+2v3=0 2v2+2v3=0 6v3=0

i'm not sure what the vector is, if v3=0, then 2v2+2(0)=0 so v2 must be 0 also and then v1+0+0=0 would mean v1 is zero too, right?

just put any value, for example v3=a and find the other

well for other eigenvalues, i have vectors with nonzero values...ok, if i plug in 3for v3, the last equation wouldn't make sense. and the answer isn't 0 vector. the vectors i have for my other values are correct

you should get a singular matrix the last row should be 0

2v2+2a=0 v2=a v1+v2+2v3=0 v1+a+2a=0 v1 = 3a eigenvector (1,1,3)

it doesn't have to be all 0

@phi is right the matrix should be singular. So you made a mistake somewhere

i was taught the bottom left triangle has to be 0s.

elica85Best ResponseYou've already chosen the best response.0
so it would be the bottom left corner, and the values right above and to the right

i've checked and checked to see if i made a mistake...i will look again

i think your eigenvalue is wrong
