WebJan 17, 2024 · A vector field is said to be continuous if its component functions are continuous. Example 5.2.1: Finding a Vector Associated with a Given Point Let ⇀ F(x, y) = (2y2 + x − 4)ˆi + cos(x)ˆj be a vector field in ℝ2. Note that this is an example of a continuous vector field since both component functions are continuous. Webwe use Circc (F) and Fluxc (F) to denote the circulation of F on C and the flux of F across C respectively. In R3, let F be a continuous vector field and C be a smooth oriented simple curve.

Intuitively this is summing up all vector components in line with the tangents to the curve, expressed as their scalar products. For example, given a particle in a force field (e.g. gravitation), where each vector at some point in space represents the force acting there on the particle, the line integral along a certain path is the work done on the particle, when it travels alo… how many tablespoons equals 4 oz
