Homework Statement



The area in the region inside the unit circle and above the graph of f(x) = x^5

Homework Equations



I don't know how to type the equation in here but the area is the integral between two integration points of the higher curve minus the lower curve.

The Attempt at a Solution



I tried using the integration points 0 and 2.02381 (the farthest the graph will stretch out according to derive), but that's the area outside and under the curve, i think the question is asking for the area INSIDE the curve.
As far as I know you can't do it with respect to y because it's infinite.

Thanks.

I'm not sure why you'd be using those integration points. For a unit circle, what is the largest possible value of x and/or y? Or, maybe think about the equation for a unit circle. Where does f(x) cross the unit circle?
 
(1,1)? So it'll be from 0 to 1 correct?

If we were to do it that way, the point of intersection would be 1 and I'm guessing the radius will be on top of the curve?
So it'll be... SQRT(1-x^2) - (x^5)?
 
(1, 1) is not a point on the circle.

Finding the points of intersection entails solving the equation sqrt(1 - x^2) = x^5. If you square both sides, you get a 10th degree equation that has no easy-to-get solutions.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
