Flux measures how much of a vector field passes through a surface, often used in physics to describe quantities like electric or magnetic fields.
This section covers the integration of a line over a 3-D scalar field. A line integral takes two dimensions, combines it the sum of all the arc lengths that the line makes, and then integrates the fun...This section covers the integration of a line over a 3-D scalar field. A line integral takes two dimensions, combines it the sum of all the arc lengths that the line makes, and then integrates the functions of x and y over that constructed line.
