Best ResponseYou've already chosen the best response.5Ok so first off, just multiply the vector with the first row of this matrix. What do you get?

Best ResponseYou've already chosen the best response.5Perfect, so now we can plug this in to your vector (v_1, v_2) to get this: dw:1439629321422:dw

Best ResponseYou've already chosen the best response.5So your eigenvector is (i, 1), and the v_2 is just an arbitrary constant showing you you can multiply your eigenvector by any constant. So now multiply your vector by i and see it desn't matter: dw:1439629416364:dw

Best ResponseYou've already chosen the best response.5what's that fancy 1, like I think it's a vector with two 1s in it? dw:1439629848428:dw

Best ResponseYou've already chosen the best response.5It's ok I'll help figure it out. I know that repeated eigenvalues are weird though, so you might just have to memorize this trick, I think you just multiply by t honestly they're making it look more complicated than it should be I think cause they're retarded

Best ResponseYou've already chosen the best response.5Ok ok, so now we can multiply to get: dw:1439630308680:dw I think that should work

Best ResponseYou've already chosen the best response.5oh ok I forgot to include that! I realized that fancy 1 was the identity matrix: dw:1439630629121:dw then plugging in from there we have: dw:1439630686461:dw so that's what leads to this step here: dw:1439630539112:dw I kinda skipped some steps but circle anything else that bothers you so I can explain it more. ;)

Best ResponseYou've already chosen the best response.0It is not clear how to proceed other than "pattern match" \[ \dot{x}_1 =x_1+x_2\\ \dot{y}_1= y_2 \] and try \(y_2= x_1+x_2\) from which we get \( \dot{y}_2= \dot{x}_1+ \dot{x}_2\) also, the second equation is \[ \dot{x}_2 =2x_1x_2\] adding this to the first \[ \dot{x}_1 =x_1+x_2 \] we get \[ \dot{x}_1 +\dot{x}_2=x_1+x_22x_1x_2 =x_1 \] or, using our "guess" \[ \dot{y}_2=  x_1 \] which is consistent with \(y_1= x_1\) in other words, make the substitutions \[ x_1= y_1 \\ y_2= x_1+x_2 \rightarrow x_2= y_2 y_1\]
