Homework Statement
a: In plane polar coordinates, find the scalar product of the vector (0,1) with itself.
b: What would be the r, θ components of the unit vector in the θ direction?
Homework Equations
Scalar product of 2 vectors = AαgαβBβ
The Attempt at a Solution
For part a, I used the equation above to determine the scalar product of (0,1) with itself is r2.
Assuming that's correct, I'm really stuck on part b and not sure what to do.
