Extreme Values Ex.5_1
1. Insert P(a) = a² + 128 / a and press on the Enter key to draw the area of the bottom and the walls P as a function of the side α of the bottom
2. Insert P'(a)=Derivative(P) to draw the first derivative of the function
3. Notice that when a=4 (the x-coordinate of the point Extrem) and V=32m³ (the y-coordinate of the point Extrem) the area P has minimum value
