Vectors Flashcards
1
Q
What is a vector
A
A representation of a geographical space
2
Q
What is the convex combination of vectors
A
w = αu + βv;
where α,β >= 0 and α and β = 1
Finds the ratio of the vector of u and v from the point w
3
Q
What is the dot (scalar) product
A
u.v = |u|.|v| cosθ
Can be used to find angle between two vectors
Or:
u . v = u
