Use MATLAB to solve this problem: Find the extreme values of the function f(x; y) = x^2*y on the curve x^2+2*y^2 = 6: Sketch the given surface and show the extreme values.

Can you help me with MATLAB code?
Thanks

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
