Hi

I was wondering what the two numbers within a translation vector are called? Are they just called the horizontal movement and the vertical movement or something else??

Thanks in advance!

I'm making up these names for fun:

X-component = vector magnitude times cosine of angle with X-component direction

sin theta = cosine(90-theta) for theta between 0 and 90 anyway, I do everything in 1st quadrant anyway.

X-component also is vector magnitude times sine of angle with Y-direction.

And Y-component is Vector Mag times cosine of angle with Y-direction,

and also Y-component is Vector Mag times sine of angle with X-direction.
