Homework Statement
Show that if {a, b, c} is a linearly independent set of vectors, then so are {a, b}, {a, c}, {b, c}, {a}, {b}, and {c}.
Homework Equations
None.
The Attempt at a Solution
Well I was just thinking that if {a, b, c} is a linearly independent set of vectors, then {a, b, c} span R3. And so if {a, b, c} span R3, then {a, b}, {a, c}, and {b, c} must span R2 and be linearly independent, and {a}, {b}, and {c} span R1 and be linearly independent. That's all I got. How could I prove this mathematically?
Cheers!
