1. (1013115) One use of linear approximation in math, science, or economics is to replace a more complicated function with its linear approximation at a point P, when you know you're working with points close to P. This makes computations and other analyses easier. For example, in physics, you'll often see when working with a small value of a: near 0, physicists will use that sina' m a}. For a chemistry example, see below1 Here we'll do this for the function \"9319): Vy+C032$- Find the linear approximation function (aka linearization) for x, 3;) at (O, 0). Then use the linear approximation function (linearization) to approximate f(0.1, 0.1). 2. Find all the (local) maximum and minimum values and saddlepoints of the function. ay) = ey($2 - 92) Be sure to justify your classication
