Could someone please help me simplify this so I can integrate it

  1. Sep 1, 2004 #1
    I have to integrate:

    sqrt( (3t^2)^2 + (1)^2 + (sqrt(6)t)^2 ) at the limits t=1 and t=3

    I cant figure out how to simplify the problem so that I can do the integral.

    So far the farthest I've gotten is the obvious:

    sqrt( 9t^4 + 6t^2 + 1 )

    now im stuck.

    wow, nevermind. I'm such a tool. I didnt realize all that under the sqrt came out to be ( 3t^2 + 1 ) ^2

    then your problem is indeed solved.
