Area of a 2D region (Green's Theorem)(?)

Click For Summary
SUMMARY

The discussion centers on calculating the area of the region defined by the equation x³ + y³ = 3xy using Green's Theorem. The area is computed using the formula Area = 1/2 ∫(x dy - y dx) with the parametrization γ(t) = <3t/(1+t³), 3t²/(1+t³)>. The user confirms their approach by substituting the parametric equations into the area formula and seeks validation of their method, which is indeed correct for this application of Green's Theorem.

Homework Statement


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

Homework Equations



Area = 1/2 [tex]\int[/tex]x*dy - y*dx

The Attempt at a Solution



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