Exact Equations and Integrating Factors
Which is a first order differential equation. The goal of this section is to go backward. A differential equation with a potential function is called exact. If you have had vector calculus , this is the same as finding the potential functions and using the fundamental theorem of line integrals. Does this method always work?
By means of this approach, a few fractional differential equations are successfully solved. As a result, some new Jacobi elliptic function solutions including solitary wave solutions and trigonometric function solutions are established. The proposed method can also be applied to other fractional differential equations. Fractional differential equations attracted attention in physics, biology, engineering, signal processing, systems identification, control theory, finance, and fractional dynamics [ 1 — 3 ]. Also, they are employed in social sciences such as food supplement, climate, finance, and economics. Finding approximate and exact solutions to fractional differential equations is an important task.

You should have a rough idea about differential equations and partial derivatives before proceeding! Note: f y is our version of the constant of integration "C" because due to the partial derivative we had y as a fixed parameter that we know is really a variable. That "C" can be a different value to the "C" just before. Some equations that are not exact may be multiplied by some factor, a function u x, y , to make them exact. When this function u x, y exists it is called an integrating factor.

Вопросы, не имеющие ответов, множились в голове. А теперь все по порядку, - произнесла она вслух. К Хейлу можно вернуться чуть позже. Сосредоточившись, Сьюзан перезагрузила Следопыта и нажала клавишу ВВОД.
ГЛАВА 36 Ручное отключение.
- Позволь мне кое-что проверить, - сказала она, перелистывая отчет. Найдя то, что искала, Мидж пробежала глазами цифры и минуту спустя кивнула: - Ты прав, Чед. ТРАНСТЕКСТ работал на полную мощность.
Снова и снова тянется его рука, поблескивает кольцо, деформированные пальцы тычутся в лица склонившихся над ним незнакомцев.
