Textbook Problem

Use traces to sketch and identify the surface.

4*x*^{2} + 9*y*^{2} + 9*z*^{2} = 36

To determine

**To identify**: The given surface equation and sketch it.

Explanation

**Given data:**

Surface equation is

**Formula used:**

Consider the standard equation of ellipsoid.

Consider the given surface equation.

Divide the equation by 36 to make RHS as 1.

By comparing equation (3) with (1), the computed expression satisfies the equation of ellipsoid.

Thus, the surface equation
