To the moderator: This isn't a HW question, but it probably sounds like one, so I appologize. Please move this to the HW forum if need be. I have an integration domain inside three intersecting curves. Two of the curves are straightlines and the third is a parabola. These three boundaries are of the form [tex] y=Ax \, \qquad y=Bx \, \qquad y=(1+x)^2 [/tex] where A and B are arbitrary constant slopes > 4. I want to transform the boundary of this domain into a triangle, as simply as possible. Any hints?
