## Math2400 one year ago can anyone tell me what's wrong in this? arc length problem

Kind of interesting, that it says you have to compute that integral. Id expect it to tell you to compute $\int\limits_{a}^{b}\sqrt{1+[y']^{2}}dx$

Unless that's what it wants you put in for your f(x), that normal arc length square root function.
