Homework Statement
Let T:Rn to Rm be a linear transformation that maps two linearly independents vectors {u,v} into a linearly dependent set {t(u),T(v)}. Show that the equation T(x)=0 has a nontrivial solution.
Homework Equations
c1u1 + c2v2 = 0 where c1,c2 = 0
T(c1u1 + c2v2) = T(0) where c1 or c2 /= 0
The Attempt at a Solution
Since we know:
T(c1u1 + c2v2) = T(0) where c1 or c2 /= 0
T(c1u1) + T(c2v2) = T(0)
c1T(u1) + c2T(v2) = T(0)
c1T(u1) + c2T(v2) = 0 (c1 or c2 /= 0)
T(x) = 0 has trivial solution
c1T(x) = 0 where c1 /= 0
I'm not sure how to connect those two ideas or if there even relevant to the solution proof.
