I'm to find the acrlength parameter for s = s(t) for the path
x = e^at cos bt i + e^at sin bt j + e^at k
I do know the formula for the arclength parameter, but I'm not quite sure how the unit vectors would fit in. The formula for arclength is
s(t) = (integral from a to t)||x'(b)||db
Do I just pretend they're not there and proceed normally? Thanks!
