Group Although there is not a set formula to follow when writing a film review, the genre does have certain common elements that most film reviews include. Introduction - In the opening of your review, provide some basic information about the film. You may include film’s name, year, director, screenwriter, and major actors. - Your introduction, which may be longer than one paragraph, should also begin to evaluate the film, and it should allude to the central concept of the review. A film review does not have to contain a thesis or main claim, but it should focus on a central analysis and assess 2nd group2) Plot Summary - Remember that many readers of film reviews have not yet seen the film. While you want to provide some plot summary, keep this brief and avoid specific details that would spoil the viewing for others. 3) Description - While the plot summary will give the reader a general sense of what the film is about. This may include your personal impression of what the film looks, feels, and sounds like. In other words, what stands out in your mind when you think about this particular film?3rd group 4) Conclusion Evaluation - The closing of your film review should remind the reader of your general thoughts and impressions of the film. You may also implicitly or explicitly state whether or not you recommend the film. Make sure to remind the reader of why the film is or is not worth seeing.Post-reading method “Speed chatting”.

x\cdot y'=x \cdot e^\big{ \frac{y}{x} }+y
Убедимся, что данное дифференциальное уравнение является однородным. 

То есть, воспользуемся условием однородности
\lambda x\cdot y'=\lambda x \cdot e^\big{ \frac{\lambda y}{\lambda x} }+\lambda y\\ \\ \lambda x\cdot y'=\lambda(x \cdot e^\big{ \frac{\lambda y}{\lambda x} }+y)\\ \\ x\cdot y'=x \cdot e^\big{ \frac{y}{x} }+y
Итак, данное дифференциальное уравнение является однородным.

Однородное дифференциальное уравнение сводится к уравнению с разделяющимися переменными относительно новой неизвестной функции u=u(x) с замены:
  y=ux, тогда y'=u'x+u
x\cdot (u'x+u)=x\cdot e^\big{ \frac{ux}{x} }+ux\\ \\ x\cdot (u'x+u)=x(e^u+u)\\ \\ u'x+u=e^u+u

u'x=e^u
По определению дифференциала, получаем
\dfrac{du}{dx} \cdot x=e^u - уравнение с разделяющимися переменными.
Разделим переменные.
\dfrac{du}{e^u} = \dfrac{dx}{x} - уравнение с разделёнными переменными.

Проинтегрируем обе части уравнения
\displaystyle \int\limits { \frac{du}{e^u} } \,=\int\limits { \frac{dx}{x} } \\ \\ \int\limits {e^{-u}} \, du=\int\limits { \frac{1}{x} } \, dx
-e^{-u}=\ln |x|+C - общий интеграл новой функции.

Таким образом, определив функцию u из решения уравнения с разделяющимися переменными, чтобы записать решение исходного однородного уравнения, остаётся выполнить обратную замену: u= \dfrac{y}{x}

То есть, 

-e^\big{-\frac{y}{x} }=\ln |x|+C - общий интеграл исходного уравнения.
Остаётся определить значение произвольной постоянной C. Подставим в общий интеграл начальное условие:
-e^\big{-\frac{0}{1} }=\ln |1|+C\\ C=-1

-e^\big{-\frac{y}{x} }=\ln |x|-1 - частный интеграл, также является решением данного дифференциального уравнения.

ответ: -e^\big{-\frac{y}{x} }=\ln |x|-1
