1. The problem statement, all variables and given/known data Given: R(t)= <(1/2)t^2, (4/3)t^(3/2), 2*sqrt(3)t> Find: Arc length function s(t) where t_0 =0 2. Relevant equations Is this the correct formula? ∫[0,t] sqrt( derivative^2 + derivative^2 +derivative^2) dt ∫[0,t] sqrt(t^2 + 4t + 12) dt 3. The attempt at a solution ∫[0,t] sqrt(t^2 + 4t + 12) dt I am not looking for anyone to do my homework, but before I start a messy integral I just want to know if: A) I am starting correctly, and B) if their is an easier way to do this (or strategy) Thanks.
