Step-by-Step Analysis
We start by restating what is given and then compute each requested derivative step by step so you can see how the values are obtained. Function: f(x, y) = x^2 y^2 + y e^{x-1}. a) Partial derivatives at (1, 1) - ∂f/∂x: Differentiate f with respect to x, treating y as constant. The term x^2 y^2 gives 2x y^2. The term y e^{x-1} gives y e^{x-1} when differentiating with respect to x. Thus, ∂f/∂x = 2x y^2 + y e^{x-1}. Evaluate at (1, 1): ∂f/∂x (1,1) = 2(1)(1)^2 + (1) e^{1-1} = 2 + 1 = 3. So the numeric value is 3. - ∂f/∂y: Differentiate f with respect to y, treating x as constant. The term x^2 y^2 di......Login to view full explanation
