To find the extreme values of a function f(x,y) on a curve x= x(t), y = y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. As in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. Find the absolute maximum and minimum values of the following function on the given curves. Use the parametric equations x = 2 cost, y= 2 sin t. Functions: Curves: i) The semicircle x + y? = 4, y20 ii) The quarter circle x? +y? = 4, x20, y 20 а. f(x.y) = x+y b. g(x,y) = xy c. h(x.y) = 2x2+ y? a. On the semicircle, the absolute maximum is f=at t=D. (Type exact answers, using z as needed. Use a comma separate answers as needed.)
