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?
