Transcribed Image Text:Tangent Lines to Intersecting Surfaces
In Exercises 15-20, find parametric equations for the line tangent to
the curve of intersection of the surfaces at the given point.
15. Surfaces: x + y² + 2z = 4, x = 1
Point: (1, 1, 1)
16. Surfaces: xyz = 1, x² + 2y² + 3z² = 6
Point: (1, 1, 1)
17. Surfaces: x² + 2y + 2z = 4, y = 1
Point: (1, 1, 1/2)
18. Surfaces: x + y² + z = 2, y = 1
Point: (1/2, 1, 1/2)
19. Surfaces: x³ + 3x²y² + y² + 4xy z² = 0, dy) nearby,
x² + y² + z²
= 11
