Explanation Given information: f ( x , y ) = x 3 + y 3 x y 2 Calculation: We will calculate limit of the function by setting y = m x as follows, Substituting y = m x in f ( x , y ) = x 3 + y 3 x y 2 we get, f ( x , m x ) = x 3 + ( m x ) 3 x ( m x ) 2 = x 3 + m 3 x 3 x × m 2 × x 2 = x 3 ( 1 + m 3 ) m 2 × x 3 = ( 1 + m 3 ) m 2 Now we will find the limit of the function as ( x , y

Limits of Multivariable Functions

Multivariable calculus is an extension of single variable calculus. It involves several variables instead of just one. Assume there is an open set containing points (x0, y0), let f be a function defined in that open interval except for the points (x0, y0…
