A parametric representation of the curve of intersection of the two surfaces
x2 + 5y2 - z = 0 and z - 4y2 = 36 is given by the vector equation :
r (t) = 6cosh(t) i
+ 2sinh(t) j + (36 - 16 sin²(t) ) K ,0sts 2n
r (t) = 6cos(t) i + 2sin(t) j + (36 - 16 sin2(t) ) k , 0 st s 2n
= cos(t) i + sin(t) j' + (36 - 16 sin²(t) ) k ,0 st s 2n
%3D
r (t) = 6cos(t) i + 6sin(t) j + 36(1 + 4 sin2(t) ) k ,O st s 2n
r (t) = cos(t) i + 3sin(t) j + 36cos2(t) k ,0 st s 2A
