Sketch the curve given in polar coordinates by the equation
r = 2 + cos Ѳ
(a) Find the area of the region enclosed by the curve.
(b) Giving answers to 2 decimal places, find the coordinates of the points on the curve where the tangent is parallel to the initial line.
Iíve sketched the curve but what is the boundary? Then how can I solve these? Please help me.
