Find the absolute maximum and minimum values of the function on the given curve. f(x,y) = xy on the curve x + y = 64, x20, y20. (Use the parametric equations x = 8 cost, y = 8 sin t.) . . . O A. Absolute maximum of 32 at t= -; absolute minimum of 0 at t = 0 and t = O B. Absolute maximum of 32 at t= -; absolute minimum of 0 at t = 0 and t = O C. Absolute maximum of 16 at t= =; absolute minimum of 0 at t = 0 and t= OD. Absolute maximum of 16 at t= -; absolute minimum of 0 at t = 0 and t=
