Vector Symbol Meaning - Explained by stampede247

[stampede247]

So I am working on verlet integration using http://www.gamedev.net/reference/programming/features/verletPhys/page2.asp" algorithm. What I wanted to know was what do the symbols above the letters mean. N R and R₀ are all 2d Vectors. Anybody know?

Thanks,

hi stampede247!

i think those marks are just arrows …

you put the arrow above the letter to make it clear that the letter represents a vector (instead of a hât, putting it in bold, underlining it, etc, or simply trusting the readers to use their common-sense!)
