Curve sketching in polar coordinates
1983Open image in new window Fig. 3.1 In Fig. 3.1(a), the position of the point P is given by the position vector \( \overrightarrow {OP} \) or by the cartesian coordinates (x, y), where ON = x, NP = y, with the normal sign convention applying when P takes positions in the other quadrants defined by the axes Ox and Oy. The point P may also be given
