Recognize a vector field in a plane or in space. Sketch a vector field from a given equation.Examples of Vector FieldsHow can we model the gravitational force exerted by multiple astronomical objects? How can we model the velocity of water particles on the surface of a river? Figure 1 gives...
In this explainer, we will learn how to convert between rectangular and polar forms of a vector. When we think about vectors in the plane, we usually think of Cartesian coordinates as this is the most prevalent coordinate system, which leads to the rectangular form of a vector. In ...
