That'll do it! I think I tried something similar but I always had x to the power of something which made is messy and gross. I should have thought to do it another way - doh! Thanks so much for your help.

Homework Statement Consider the curves: y = x^2 from 1/2 to 2 and y = \sqrt{x} from 1/4 to 4. a. Explain why the lengths should be equal. b. Set up integrals (with respect to x) that give the arc lengths of the curve segments. Use a substitution to show that one integral can be...
