ok, i know how to find an eigenvalue and an eigenvector that's fine, what i don't remember is how to normalize your eigenvectors in my problem i have 2 eigenvectors, (1,3) and (3,1) (1,3) corresponds to eigenvalue 10 (3,1) corresponds to eigenvalue 20 in my notes i have written 'to...

Homework Statement the question i have is about part b). by 'a solution' does it mean what x equals? as in show that x = -(a x b)/|a|^2 is a solution?

ok i looked up slope and now know it is a number but the answer to this question still eludes me! i don't know how you'd put the equation on a graph the notes i have for this involve looking at the independence of say, x of the equation so I am rather stumped. also i just suck at graphs...

uhh i'm not sure...some kind of straight line?

Homework Statement (i'm not sure if this is the correct forum please move it if incorrect) my problem is with generally drawing direction fields - i don't really know what to do. i have notes but i can't make head nor tail of them. this is an example of a question concerning them: Homework...

erm ok, i figured that the ratio is 1/(1+x) then i subtracted the series times the ratio from the series and got s = x(1+x) is this what I'm supposed to do?

Homework Statement Homework Equations -- The Attempt at a Solution really what has thrown me here is the power of n. as we know it converges at some x, i figured i don't need to do any convergence tests. i thought about it and can only come to the conclusion that it converges at...
