Given that A = a x + 6 a y + 5 a z   a n d   B = a x + 2 a y + 3 a x
Now Scalar projection of A on B:
c o m p B A = B . A | B |
= 1 ( 1 ) + 2 ( 6 ) + 3 ( 5 ) 1 + 4 + 9
= 26 14

The problem defines:
velocity in the local base { e r , e θ , e z }, the gradient and acceleration in the local curvilignear base e i e j avec i , j { r , θ , z }
In a problem's solution, this result is used to calculate the stress resultant
σ n = [ 0 μ w / H p a t m ]
R = 0 2 π
+ 0 2 π 0 R d p a t m e z r d r d θ =
= 0 2 π ( e θ ( θ ) d θ 0 R d μ ω H r d r ( 2 π p atm 0 R d r d r ) e z
then it says 0 2 π ( e θ ( θ ) d θ = 0 which I've been stuck for one hour looking where it came from ?

Given a vector v R n then show that we can express k ω k v k 2 as a matrix product of the form v T M v. Give an expression for M in terms of ω = [ ω 1 . . . ω n ] T
I understand that here, the product of a row vector, matrix, and column vector (in that order) is a scalar. However, how do I write M in terms of ω = [ ω 1 . . . ω n ] T ?
