how do you find the length of the curve 3x = 2(y-1)^(3/2) : 2 is less than or equal to y which is less than or equal to 5. i think i have to use the arc length equation L= integral from a to b of the magnitude of the derivative of the position function, but i just don't see where the vectors are in the question to solve this. the answer in the back of the book is: (2/3)((5sqrt5) - (2sqrt2)). thanks-
