41. Since the motion is planar and the force radial, it is customary to switch to polar coordinates . 42. Sensors operate using a polar coordinate system. 43. A point in the complex plane can be represented by a complex number written in polar coordinates . 44. The LCh values are a polar coordinate transformation of what is technically defined RGB cube color space. 45. :: The Euclidean version of the special relativistic cosmology is polar coordinates , with ? being the radius. 46. C + + and polar coordinates , both of which would be represented by two floating point numbers. 47. The integrals over the two disks can easily be computed by switching from cartesian coordinates to polar coordinates : 48. In 1893 Durand published a paper mathematically describing a radial planimeter for averaging values plotted in polar coordinates . 49. In cylindrical coordinates on the sphere and polar coordinates on the plane, the projection and its inverse are 50. For example, in polar coordinates :
