Question

calculating the length of the arc curve given by x = (8/3)(t^3/2) and y = 2t - t^2 for T epsilon [1,3] what does that t epsilon mean? it's a t and the symbol for epsilon right next to each other like te[1,3]

Answer 1

\(t \in [1,3]\) means t takes on all values between 1 and 3, inclusive.
