ДАНО

Y = -x² + 4

Y = 0

НАЙТИ

S = ?

РЕШЕНИЕ

Пределы интегрирования даны

а = -2  b = 2.

Площадь интеграл разности функций.

S = \int\limits^b_a (4-x^2) \, dx= \frac{4*x}{1}- \frac{x^3}{3}

Вычисляем подставив пределы интегрирования

S(2) = 8 - 2 2/3

S(-2) = - 8 + 2 2/3

S = 5 1/3 - (-5 1/3) = 10 2/3 ≈10.667 -площадь - ОТВЕТ

I am proud of my country. This is a multi-ethnic state of Kazakhstan. It ranks ninth in world's largest site! Kazakhstan is a big state, built in a difficult environment. Are steppes, semi-deserts and deserts.

Kazakhstan gained independence about twenty years ago, after the collapse of the Soviet Union. But the national culture of Kazakhstan many centuries ago began to create the Kazakhs, nomads, who spend most of life spent in the saddle. Endless steppes and semi-deserts, overgrown fescue, feather-grass, wormwood and tercica, were their only riches.

Now our country is home to people of different cultures: Kazakhs, Russians, Uzbeks, Ukrainians, Uighurs, Tatars and others. Every resident of Kazakhstan knows the Kazakh language is the language of the Kazakh nation. Also recognized as the official language of Russian as language of interethnic communication. People in Kazakhstan live free, and not crowded. There are a lot of lands and people on them have a little.
