Question

find the cartesian coordinates of the point whose polar coordinates are (4,1/2)​

Answer 1

Answer:

For any point P, a line is drawn through P perpendicular to each axis, and the position where it meets the axis is interpreted as a number. The two numbers, in that chosen order, are the Cartesian coordinates of P. The reverse construction allows one to determine the point P given its coordinates.

Answer 2

Answer:

The cartesian co-ordinates of the point whose polar co-ordinates are as (13 ... So, by (1), x2= 144 ... Hence, the cartesian form is (−12,5).
