# Classifying a Quadric Surface In Exercises 35-48, classify the quadric surface. See z 2 = 2 x 2 + 2 y 2

To determine

The quadric surface of equation z2=2x2+2y2.

Explanation

Given Information:

The equation of the quadric surface

z2=2x2+2y2

Standard form of elliptical cone

x2a2+y2b2z2c=1

Special case, for circular cone

a=b

Consider the given equation

z2=2x2+2y2

Now, reduce in standard form

x2+y2z22=0

Above equation can be written as:

x212+y212z2(2)2=0

Above equation is similar to the standard equation of elliptic cone
