Any representation of a plane curve or space curve using a vector-valued function is called a vector parameterization of the curve.Example: Combining Vectors Create a graph of each of the following vector-valued functions: r(t)=4costi+3sintj, 0≤t≤2πr(t)=4costi+3sintj, 0≤t...
For example, the position x of a moving particle at time t, or the gravitational force F on an orbiting satellite at time t are vector functions. Top do calculus in space, derivatives of vector functions is needed. The derivative of a vector function is defined as the limit of a ...
4.1 Vector functions or space curves Vector functions (3D parametric equations) are defined and plotted similarly to 2D plots, except one must use the command instead of and instead of . Sign in to download full-size image One can fine-tune the domain used for and color(s) used, but ...
Vector Functions: Given two intersecting surfaces in 3-dimensional space, we can find their curve of intersection by finding the points which satisfy both equations. For this, we can find one coordinate from both equations and equate these...
The proof is based on a description of the monads of all locally Cohen-Macaulay space curves defined by cubic equations. We extend then this kind of classification to higher dimensional projective spaces. We use this extension to recuperate quickly the classification of globally generated vector ...
Space Curve: We often call curves that are represented by vector-valued functions space curves. All we have to do to represent a curve as a vector-valued function is find a parameterization for the curve, and then toss it into a vector {eq}\vec r (t) = \left< x (t), y...

[4,7,9] it was studied the problem of finding necessary and sufficient assumptions onto be left-invariant on a Lie group whose manifold is the entirespace. In the cited papers the vector fieldswere always required to be real-analytic, and the vector space structure of the underlying manifold...
