Question

can anyone tell me what's wrong in this? arc length problem

Answer 1

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

Answer 2

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

Answer 3

ohh ok i see let me see

Answer 4

ya i got it! it confused me when it said f(x) i thought it was simple ahaha thanks :)

Answer 5

No problem :)
