Length of Vector Function: If {eq}\vec{r}(t) = x(t) i + y(t) j + z(t) k {/eq} be a vector function then length of that vector function {eq}\vec{r}(t) {/eq} on the interval {eq}a \leq t \leq b {/eq} is represent the total path ta...
where[a,b]is the interval in which we want to get the length of the curve. Answer and Explanation:1 Let's begin by getting the derivative of the components of the vector curve. {eq}\displaystyle \mathbf R (t) = f(t) \mathbf i ...
To use the arc length formula first we find the derivative by using the chain rule. Next, we try to remove the square root in the size of the tangent vector by completing some squares. Answer and Explanation:1 Remember that the length of a curve {eq}\displaystyle \, y =...
