Polar coordinates

Builds on Euclidean space

Summary

Polar coordinates describe a point of the plane by two numbers. They are its distance rr from the origin and the angle θ\theta from the positive xx-axis to the ray through the point. They simplify problems with circular symmetry, such as integrals over discs.

Remarks

The polar form of a complex number is a related idea: see polar form.

What this page needs for W2

  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a page is. They do not measure its truth.
