Find a Parametric Representation for the Surface Consisting of the Upper

question 59

Multiple Choice

Find a parametric representation for the surface consisting of the upper half of the ellipsoid $x ^ { 2 } + 5 y ^ { 2 } + z ^ { 2 } = 1$ .

• A) \(x = x , y = y , z = \sqrt { 1 + x ^ { 2 } + 5 y ^ { 2 } }\)
• B) \(x = x , y = y , z = \sqrt { 1 + x ^ { 2 } - 5 y ^ { 2 } }\)
• C) \(x = x , y = y , z = \sqrt { 1 - x ^ { 2 } + 5 y ^ { 2 } }\)
• D) \(x = x , y = y , z = \sqrt { 1 - x ^ { 2 } - 5 y ^ { 2 } }\)
• E) \(x = x , y = y , z = \sqrt { x ^ { 2 } + 5 y ^ { 2 } - 1 }\)
• F) \(x = x , y = y , z = \sqrt { x ^ { 2 } - 5 y ^ { 2 } - 1 }\)
• G) \(x = x , y = y , z = \sqrt { - x ^ { 2 } + 5 y ^ { 2 } - 1 }\)
