How to parametrize curves

WebSummary. A function with a one-dimensional input and a multidimensional output can be thought of as drawing a curve in space. Such a function is called a parametric function, and its input is called a parameter. Sometimes in multivariable calculus, you need to find a parametric function that draws a particular curve. WebFor any given a curve in space, there are many different vector-valued functions that draw this curve. For example, consider a circle of radius centered at the origin. Each of the following vector-valued functions will draw this circle: Each of these functions is a different parameterization of the circle. This means that while these vector-valued functions draw …

Web2. Think of the given equation as the equation of a curve. Use the remaining parameter to parametrize the curve. Example. Parametrize the cylinder in R3 given by x2 +y2 = 1. Notice that in 2 dimensions x2+y2 = 1 is the equation of a circle. The equation does not involve z, so I set z = v. Next, I must parametrize x2 +y2 = 1. I can use the ... WebIf we keep the first parameter u constant, then v → ~r(u,v) is a curve on the surface. Similarly, if v is constant, then u → ~r(u,v) traces a curve the surface. These curves are called grid curves. A computer draws surfaces using grid curves. The world of parametric surfaces is intriguing and complex. WebApr 11, 2024 · Non-free curves on Fano varieties.
