I have a function here...
r(t) ={6Sqrt[2]t, 3Exp[2t], 3Exp[-2t]}
I needed to find the norm of r'[t]... yet when Mathematica tries to simplify it, it can't do it with simplify, powerexpand[simplify[]], fullsimplify... and this function IS suppose to be able to simplify. I then started running through every basic algebraic manipulation tool and came up empty...
I restarted mathematica thinking the kernel had just given up on me but that didn't work.
PowerExpand[Simplify[]] gives me 12Cosh[2Re[t]] and that can't be it...
Someone think they know what's going on here?
