what is the area inside the graph of r=2sinθ and outside the graph of r=sinθ+cosθ? so i compute for the values of 'r',... but, i only got one intersection point which is (45°, 1.41). there must be two intersection points right? but i've only got one. what shall i do? i cannot compute for the area of the said region because i've only got one limit which is ∏/4.. what shall i do? please help.. thanks a lot..
