Determinant - Proof for distinct real numbers

Click For Summary
SUMMARY

The discussion centers on proving properties of determinants for distinct real numbers, specifically addressing the challenge of proving part b of a problem. The participants suggest utilizing the geometric interpretation of determinants and reference the Vandermonde matrix as a potential resource. A key insight shared is that a determinant equals zero if its columns form a linear combination, which is crucial for understanding the proof.

I was able to prove a), but I am unsure how to prove b. Is there some sort of geometric interpretation I should be aware of?

Hey Rido! ;)

One way is apply the property of a determinant that it is 0 iff its columns form a linear combination. (Thinking)
