determine the highest point and lowest point of the ellipse of intersection of the cylinder x ^ 2 + y ^ 2 = 1 and the flat 2*x+y-z=4 .The person who can tell me how to compute is or who can solve it plase help me !! Thank you in advance!

Question

determine the highest point  and lowest point of the ellipse of intersection of the cylinder x ^ 2 + y ^ 2 = 1 and  the flat 2*x+y-z=4 .The person who can tell me how to compute is or who can solve it plase help me !! Thank you in advance!

anonymous · Answer

the intersection is an elipse juste plug y = 4 - 2*x in the circle equation
