Measurable Success can be measured by the number of applications, interviews and job offersSection 16 Vector Functions We first saw vector functions back when we were looking at the Equation of LinesIn that section we talked about them because we wrote down the equation of a line in \({\mathbb{R}^3}\) in terms of a vector function (sometimes called a vectorvalued function)In this section we want to look a little closer at them and we also want to look at some vector functionsDefinition In the case of a space curve, the radius of curvature is the length of the curvature vector In the case of a plane curve, then R is the absolute value of ≡ =, where s is the arc length from a fixed point on the curve, φ is the tangential angle and κ is the curvature Formula In 2D If the curve is given in Cartesian coordinates as y(x), then the radius of curvature is 2 Y=a(1+r)^t examples
