Show that the curve with vector equation
is the curve of intersection of the surfaces and .
Attempt:
(1)
(2)
plug (1) into (2) for y
Expanding and canceling
(3)
vector equation
(4)
plug (4) into (3)
divide out the 4
identity
therefore 1= 1
Did i even do this correct?
If not where did i go wrong?
Thank you
