Vectors

Question 1

What is a vector

Answer 1

A representation of a geographical space

Question 2

What is the convex combination of vectors

Answer 2

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

Question 3

What is the dot (scalar) product

Answer 3

u.v = |u|.|v| cosθ
Can be used to find angle between two vectors
Or:
u . v = u
