Sphericalplot3d has attribute holdall, and evaluates the only after assigning specific numerical values to variables. The applet is similar to graphit, but instead allows users to explore the representation of a function in the polar coordinate system. See how two vectors are related to their resultant, difference and cross product. The demo above allows you to enter up to three vectors in the form x,y,z. Now, polar coordinates, most of you have studied before, it is just a different way of representing a point in the x,y plane using a length and an angle as opposed ot a length and a length, the x and the y.

One can translate between the two descriptions as follows. A vector pointing straight up has an angle of 90 degrees. Create a vector map with a grid file surfer can create vector plots from a single grid file, or from two grid files individually containing direction and magnitude information in either polar or cartesian coordinates. Regardless, the first three arguments to quiver3 are the origins of the arrows and the last three arguments are the directions the arrows go. Its very useful for teachers and s tudents to teach. Integration of a vector field in polar coordinates. The main thing missing is the norwegian pixel style. For now a nice way to plot noncartesian fields is to use transformedfield which handles scalar, vector and even tensor fields.
