how do i solve an arc length using the trapezoidal rule?

Question

anonymous · Answer

Using the Trapezoid Rule with n = 8 to approximate the arc length of the graph of $$\sqrt{36x^4-24x^2+4}$$ from A(0,1) to B(2,13) you get (to three decimal places):

Sorry I'm not familiar with the trapezoidal rule.

isn't there anyone that can help????????

mathmale · Answer

Have you studied "arc length" specifically?  If so, are you familiar with the concept of "derivative" as required by the arc length formula?

Sorry...OpenStudy is very slow right now, and I see you're "just looking around" on this site (not that I blame you, given all the delays).  There's not a lot I can do to help you without first finding out whether you're familiar with derivatives and the arc length formula (which involves integration.)
