Horizontal Tangent PlaneIn Exercises 37–42, find the point(s) on the surface at which the tangent plane is horizontal.

To determine

**To calculate:** The function is

Is given, find point on the surface at which the tangent plane is horizontal.

**Given:**

The function is

**Formula used:**

Tangent plane is horizontal at the point where slope of the plane would be zero.

Therefore,

**Calculation:**

Let us partial differentiate the function with respect to

Equate it with 0 to get,

Multivariable Calculus
