suppose I have two vectors, one in the

*i*direction and the other in

*j*direction,

*i*is horizontal and

*j*vertical.

The first vector

*Vi = 5i*and the second vector

*Vj = 2j*.

If we sum this vectos it results in one vector that have module and phase.

I found the module by

*Vij = ( 5^2 + 2^2 ) ^ (1/2) = 5.3852*.

But what about the phase?

I think it was

*atan(y/x)*, but in case

*y=0*or

*x=0*, it let me in troubles.
