Consider the region defined by 0<=y<=1/x^3 and 1<=x<=2
1) Find the value of some c so that the line x=c splits this region in halves with equal areas
2) Find the value of some d so that the line y=d splits this region in halves with equal areas.
I got 1) by doing the integral of 1/x^3 from 1 to 2 with respect to x. This gave a total area of 3/8. So then I took integral of 1/x^3 from 1 to c and set this equal to 3/16 and solved for c to get c=2sqrt(2)/sqrt(5).
I am having trouble with 2). I am trying to figure out what the integral will be. I now it is with respect to y. I believe it should be from y 0 to 1 of 1/(y)^1/3, but this does not give the necessary area of 3/8. Once I find out what the integral for the total area should be, it should be easy to find the line y=d as I did in 1). What I need help with as writing this integral with respect to y, so that I got the correct area of 3/8 (unless you know that my 3/8 is wrong and I did the first integral wrong.)
