Hello, everyone!

My name is Nic, I'm taking Math 230 (Calculus 3) currently and it is not going well. Former math undergraduates have told me Calc 2 is the hardest.....I strongly disagree

So, here's where I'm at:

7. Find the length of the curve correct to four decimal places: r(t) = <t

^{2}, t

^{3}, t

^{4}>, 0<=t<=2

Where I'm at:

L = int(a to b){|r'(t)|}

x = t

^{2} => 2t

y = t

^{3} => 3t

^{2}
z = t

^{4} => z' = 4t

^{3}
L = [(2t)

^{2}+(3t

^{2})

^{2}+(4t

^{3})

^{2}]

^{0.5}
L = [4t

^{2}+9t

^{3}+16t

^{4}]

^{0.5 }Now, I hit a wall. Can anyone assist?
