Question

find the area that lies inside both curves r=1cost and r=1-cost

Answer 1

What do you mean?

Answer 2

find the area of the region that lies inside both curves r=1+cost and r=1-cost

Answer 3

where r is the y axis and cost is the x axis and cost ranges from -INFINITY to +INFINITY ?

Answer 4

Is the region supposed to be bounded by the x-axis (the cost-axis) as well? Because otherwise the area is infinitely large.

Answer 5

well, thats the original Q... it doesnt say anything more to it
