QUESTION:
7-18. Arc length calculations Find the length of the following two- and three-dimensional curves.
\(\mathbf{r}(t)=\langle 2+3 t, 1-4 t,-4+3 t\rangle, \text { for } 1 \leq t \leq 6\)
ANSWER:Solution 11E
Step 1:
In this problem we need to find the length of the curve
r(t) = , for 1
The arc length is denoted by L , and the arc length of r(t) from a to b is defined as ;
L = …………….(1)
r(t) =
Then
=
