It is a correction for the answer to the normal component in "Find the tangential & the normal component of..."?
Correction: it should be that c=|r'xr"|/|r'^3|=>c=6t^2/[t^3(4+9t^2)^1.5]=>c=6/[t(4+9t^2)^1.5]. Thus, cv^2=6(4+9t^2)t/(4+9t^2)^1.5=>cv^2=6t/sqr(4+9t^2)=
the normal component. Sorry.Mathematics11 months ago
