Abstract
The well known fact that differentiable functions may have local extremes only at points where their first derivatives vanish is illustrated. In some cases the corresponding equations are not directly accessible or solvable and other considerations have to be applied. Constrained extremal values for real functions of several variables and extremal problems of non-differentiable functions are included.
