My question is about vector addition in cylindrical coordinates:

Let

In cylindrical coordinates,

Ar = Ax(

Br = 2.236, Bθ = 0. So B = 2.236

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

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

Let

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

**x**=**r**cosθ +**θ**sinθ,**y**=**r**sinθ +**θ**cosθ**A**=Ax**x**+ Ay**y**, B =Bx**x**+ By**y**Ar = Ax(

**x.r**) + Bx(**y.r**)=2.236, Aθ = 0. So A = 2.236**r**Br = 2.236, Bθ = 0. So B = 2.236

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

**r**+2.236**r**!!!!!Attached is the hand written file for clearer description.
