I believe that it is not necessary to live in wedlock, though many think otherwise. Any age for marriage, only if it is a solid solution of both parties, or simply impossible to live without each other. I think that the age of 25-30 years is the best for marriage.

Each family can decide how many children they want to achieve harmony. I think that divorces are caused because of the irresponsibility, but it also happens that people are disappointed in each other. I do not think it is a curse, although it may be

у ' = -sin2x*2-4cosx, y'=0 значит -sin2x*2-4cosx=0
-2*2cosxsinx-4cosx=0
-4cosx(sinx+4)=0
-4cosx=0 sinx=4-нет корней
cosx=0
х=пи/2+пи *n, n принадлежит z
- пи/2 +
убывает возрастает
ответ: пи/2+пи *n, n принадлежит z
