So the two curves are r = sin x and r = cos x
The intersecting point is pi/4 which makes r = 1/sq rt 2
now I know A = 1/2 integral sign (S) a? b? r^2 dx
The question is what is a and b equal to? I am thinking that b could equal pi/4 and then I can multiply by 2 to get the full area but I don't know how to figure out what a would
hopefully I have given you all the info you need to help me.
Now I actually figured out the pi/4 part while I was waiting for someone to guide me but I don't know how you picked the other boundary.
I was going to use a = c for one b = c for the other and then subtract the area of one from the area of the second to get the overlap..... but obviously I am missing the obvious.
By the way Skeeter you are my hero in this calculus world. My husband suggests I find out what you would like for Christmas.
