How do I go about finding this? The example in the book isn't very helpful here because they have a graph of the two surfaces and can tell what x and y are just by looking at the graph. What is a good
analytical way to arrive at the answer every time?
**********************************
Well the short answer has three steps 1) substituting one equation into the other to get a single equation in two variables, 2) remember what you learned in Calc2 about parameterizing plane curves, then 3) re-substitute your parameterization of a planar curve back into 3-D to get your intersection
Try that and let me know how it goes and what you try, I'll post your answer here.
