y= 2x – x 1\2 – sinx
y= cos6x – (2x) 1\3
Y= 3 – x\3+ 2\cos 2 x
y= 1\x 2 , (1\2; 1\3)
Y= x- x -1\2 , ( 1;4)
Y= ( x-1)\ x 1\2 , ( 1;9)
The sky all winter was gray. And now the sky was Bogolubovo and as if alive. It was filled with the voices of migrating birds. Each flock of birds returns to the place where departed.The first to return Home the rooks. Then, fly starlings, larks, ducks and geese. Later there will be cuckoos, Swifts, swallows, storks and other migratory birds. Birds make a very great journey to return home.
Birds build new nests or repair old using twigs and sticks. Because many birds had left their nests here when flew South. Then hunger and cold forced them to leave their homes. Amongst the fresh foliage the birds are preparing to withdraw in their nests birds.
