Abstract

Methods of application of differential problems Studying sections of mathematics, we can consider solving problems using mathematical apparatus, such as methods of calculation of dangerous situations, selection of the optimal portfolio, problems of optimal use of resources, analysis and forecasting of time series [2]. Let's take a closer look at the application of differential equations. Differential equations-a branch of mathematics that studies the theory and methods for solving equations with derivatives of different orders of one argument (ordinary differential) or several arguments (differential equations) [1]. The balancing involves not only the unknown function, but also its various derivatives. A differential equation describes the relationship between an unknown function and its derivatives. Such relationships are found in various fields of knowledge: mechanics, physics, chemistry, biology, economics, etc. Differential equations are used to mathematically describe natural phenomena. For example, in biology, differential equations are used to describe a population; in physics, many laws can be described using differential equations. Differential equations are widely used in economic dynamics models.These models show not only the dependence of variables on time, but also their dependence on time.We can consider one of the problems of macroeconomic dynamics [1].


For example, y(f) – the amount of output of an industry sold over time, i.e. assume that all output produced by the industry is sold at a certain price p, i.e. the condition of unsaturation of the market is satisfied.
Then set the amount of investment to expand production through income at time t and P. In the natural growth model, the rate of output (acceleration) is proportional to the amount of investment, i.e. Y (t)=py (t)
Where I(t) is the rate of acceleration. (Here we ignore the time between the end of the product and its sale, i.e. we assume that the investment lag is zero.) Assuming that the value of investment I(t) is a fixed part of income, we obtain is the coefficient of proportionality m (the so-called investment rate), which is a constant (10).
Substituting the latter expression into the Formula y(t)=y0ek(t-t0), the resulting differential equation-solving it with divisible variables, we arrive at a function whose equation y0=y(t0) also describes population growth, the dynamics of price growth with steady inflation, the process of radioactive decay, etc.
