Hi I don't understand how they did the inverse for this and how 1/54 was made

these are also a few more useful files
I am usually pretty good and I understand how to do a b and c
I just dont understand how to do the determinats and inverse to end up with that answer
old onyx
do you know how to do determinant of 2x2 matrix ?
nimble rune
do you know how to do determinant of 2x2 matrix ?
yes
i got the determinant for my 3x3
but its 486
based on the transition matrix
wait im confused
I just did the inverse
the 1/54 is the factored out
wait is that it
omg
I did it
holy shit
old onyx
i was just redoing the calcul
nimble rune
i was just redoing the calcul
omg
thank you so much
I dont understand where determinants are important for this problem at least
nimble rune
yeey good job
im sorry
to bother u again
but I keep getting 5/54
instead of -2/9
old onyx
okey wait a sec
nimble rune
oh my bad 68 not 34
thank you
I checked my work and im struggling so I genuinely appreciate it
nimble rune
Yeah thank you
nimble rune
if u need further help lemme know
oh
i do
im sorry if this wasn't clear
but 34/27 and 5/54
are not apart of the answers
but I got the -31/9
old onyx
aah okey wait
nimble rune
so i got 1 out of 3 right
old onyx
do you have the cofactor matrix ?
nimble rune
i dont
do we need that?
OH
wait
hold on
wait
is the terminiology for inverse wrong
old onyx
i guess u just have a small mistake in the inverse
nimble rune
oh were u able to reproduce it?
this is a nicer example of the inverse I found but 1/54 was taken out
regardless it should've ended up with the answer inverse
cofactor matrix was relatively new we just learned on monday so i wanted to do it via just an identity matrix
old onyx
for me i used the formula 1/det(A) x Adj(A)
the adj(A) is the transpose of Cofactor
does it make sense so far ? can i continue ?
old onyx
1 min i ll share with u my work i ll organise it as i explaine
nimble rune
thank youuu
