Homework Statement
Right I won't bore you with a sob story but this is a regular grade 12 class and we've been posed with this problem:
Find the arc length of this function across first 5 seconds (t = seconds)
s(t) = t3 - 6t2 + 9t + 5
I learned the formula of s = Integral of (1+f'(x)^2)1/2 * dx
So I began using the Riemann sums until I get here, I'm not quite sure how to proceed.

If need be I will show how I got up to there, it just takes forever to use LaTeX.
PS: That should be x->infinity
Thanks!
