Approximate the arc length of the curve y=(1/4)x^4 over the interval [1,2] using the Trapezoidal Rule T8.
I was never taught how to use the Trapezoidal Rule, so I was surprised to find this problem in my most recent Calculus assignment. How would you solve a problem like this?
Thanks in advance to anyone who's willing to help out.
