Transforming from Cartesian coordinates uses the relationships tangent of theta equals y over x, r squared equals x squared plus y squared.
When integrating over them, one should remember to multiply the function by the variable that appears in transformation. Used to express the Mandelbrot set, they come about because the unit of incremental area increases with distance from its origin. Transforming from Cartesian coordinates uses the relationships tangent of theta equals y over x, r squared equals x squared plus y squared. For 10 points—identify this coordinate system, which expresses points in terms of angle and distance from the origin.
