Document Summary
Provide a generalization to each of the key terms listed in this section. A ray with a vertex at the pole in the polar coordinate system Any point with (r, ) as their respected polar coordinates, which has in ra- dians, can represent by either (r, + 2 k) or ( r, + + 2 k), which notes k as any integer. On the other hand, (r, ) are also the poles polar coordinates, which notes that being any possible angle. Rectangular coordinates : (x, y) x = r cos y = r sin . 6. 1 plot the point, which will be labeled (x, y). 6. 2 make a note on which quadrant that the point is lying. 6. 3 make a note on which coordinate axis that the point is lying. 6. 4 find the distance, which is r, from the origin to the given point. 7. 1 plot the point, which will be labeled (x, y).
