I have two questions for you.
Typically when trying to find out if a set of vectors is linearly independent i put the vectors into a matrix and do RREF and based on that i can tell if the set of vectors is linearly independent. If there is no zero rows in the RREF i can say that the vectors are linear independent.
I Done the RREF of -> C = {(−2, 3, 0, 1),(2, 0, 3, 1),(0, 3, 3, 2)} and have gotten
1,0,1,0
0,1,1,0
0,0,0,0
0,0,0,0
Leaving me to the conclusion that it is not linearly independent.
Is there another way i could of proved it was not linear independent?Also my second Question here,
vector space V = {f : R → R}, prove that the set {2x^4 ,sin x, cos 3x} is linearly independent.
How would i go about proving that this is linear independence since i am unable to do my RREF with this?
Thanks
