<p>Context. In this paper we propose the dedetermination as the new method designed to solving a problem of calculation of deterministic<br />functions with the so-called singular points where the function does not take a certain value.<br />Objective. The approach is developed that allows for division by zero and thus exclude singular points of functions.</p><p>Method. The method proposed in this article is to move from the problematic (from point of view of calculating) determined function to the corresponding not determined (interval) function by replacing determined function parameters by corresponding interval parameters.<br />Due to this change values of the function at the singular points will be well-defined interval and values.<br />Results. The latter allows you to solve the problem of calculating the function. For the simplified by cutting out interval function the<br />effective formulas are derived based on main provisions of interval mathematics and make it easy to calculate value of this function. The<br />proposed in the article approach to the problem of calculating functions with singular points is important for all those classes of systems in<br />which the problem really exists. It is about the systems which functions have any number of specific points. Such systems are found mostly in<br />telemetry, reliability theory and practice, humanitarian and others areas. The features of these areas is that they do not always apply the<br />classical methods of deterministic mathematics. This leads us to search for new approaches to solving problems that arise here.<br />Conclusions. The solution to this problem is achieved by legalization division by zero by intervalization of calculations. It uses the<br />principle of cutting out a neighborhood of zero in the interval being the denominator of the fraction representing studied function.</p><p> </p> |
