Question

OHHH i need help in finding if a vector is linearly dependant or not

Answer 1

S=(x^2,x^2+1)

Answer 2

This is a set in P_2

Answer 3

hehe u came i was abt to log off

Answer 4

Just in time!
this can be written with just coefficients to check to see if the equation\[A\vec x=\vec 0\]has more than one solution:\[c_1+c_2=0\]\[c_2=0\]the solution to the system is the trivial solution c1=c2=0, so it's linearly independent

Answer 5

how one vector could be dependent

Answer 6

also you can note that you can't produce the second vector from the first

Answer 7

you should give 3

Answer 8

I assumed that was two vectors
is it one?

Answer 9

lol i think it is one but maaybe it is 2

Answer 10

well either way it's independent
as ackhat said one vector cannot be dependent

Answer 11

true Thanks turing have a nice weekend

Answer 12

likewise
