Question

Can someone check my results?

Answer 1

I find i) to be linear independent.

Answer 2

ii) dependent

Answer 3

iii) dependent

Answer 4

@amistre64 Can you help me?

Answer 5

ii is dependant by default, whenever you have more vectors than parts in a vector you can always make one from the other 2

if the determinant of a nxn matrix is zero, its dependant, otherwise its INdependant

Answer 6

since 4-6 is not zero, that ones INdep just need to chk iii

Answer 7

i get a zero determinant for iii so dependant

Answer 8

Great.
