WebThe first partial derivatives as to z (the variable to be maximized) are zero at the maximum (the glowing dot on top in the figure). The second partial derivatives are negative. These are only necessary, not sufficient, conditions for a local maximum, because of the possibility of a saddle point. WebIn calculus, you'll have to learn to identify the extrema (that is the general term for either max or min) by taking the first derivative. The extrema of a continuous function can only lie at one of these places: 1. Where the first derivative equals zero. 2. Where the first derivative fails to exist. 3. The endpoints of a closed interval. solved electromagnetic problems
