My question is about vector addition in cylindrical coordinates:(adsbygoogle = window.adsbygoogle || []).push({});

LetA= 2x+y,B=x+ 2y. In rectangular coordinates,AB=B-A= -x+y

In cylindrical coordinates,x=rcosθ +θsinθ,y=rsinθ +θcosθ

A=Axx+ Ayy, B =Bxx+ Byy

Ar = Ax(x.r) + Bx(y.r)=2.236, Aθ = 0. So A = 2.236r

Br = 2.236, Bθ = 0. So B = 2.236r

How do you do vector addition in cylindrical coordinates? A + B = 2.236r+2.236r!!!!!

Attached is the hand written file for clearer description.

I don't know how to add the two vectors totally in cylindrical coordinates because the angle information is not apparant. Please tell me what am I doing wrong.

Thanks
