Homework Statement


Calculate the area of the region within x3 + y3 = 3xy. It can be parametrized by \gamma:[0,\infty] \rightarrow R2 with \gamma=<3t/1+t3, 3t2/1+t3>.

Homework Equations



Area = 1/2 \intx*dy - y*dx

The Attempt at a Solution



My plan is to take the curve parametrized by \gamma=<3t/1+t3, 3t2/1+t3> and use the parametric equations as x = 3t/1+t3 and y = 3t2/1+t3. Then i simply just use the equation for area given by Green's Theorem Area = 1/2 \intx*dy - y*dx and compute the integral. Can anyone confirm if this is right or am I way off?

That should work like a charm.:smile:
 
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...
