Помимо идеальной подготовки домашних заданий, подросток сможет самостоятельно осваивать новые темы, выполнять диагностику своих знаний и восполнять в них пробелы, повторять и закреплять изученный материал. При этом ребенку не понадобятся дополнительные консультации педагога. Со всеми вопросами и темами текущего учебного года он справится самостоятельно. </p> <h2> Что готовит школьникам алгебра в 10-11 классах </h2> <p> Алгебру можно назвать лидером среди всех учебных дисциплин по количеству изучаемых тем. В десятом и одиннадцатом классах все усложняется тем, что помимо новых разделов, ребятам предстоит огромная работа по повторению ранее пройденного материала, ведь в конце года всех их ждет сложнейшее испытание - итоговый экзамен по предмету. Но его результат будет зависеть от того, насколько хорошо ребята освоят следующие разделы: </p> <ol> <li>Тригонометрические функции.</li> <li>Производная и её применения.</li> <li>Первообразная и интеграл.</li> <li>Показательная и логарифмическая функции.</li> <li>Действительные числа.</li> <li>Функции. </ol> <p> Материал очень насыщенный и достаточно сложный. При этом недостаточно будет просто вызубрить массу формул и правил. Простое заучивание - это лишь часть работы. Главное научиться применять полученные знания на практике. Именно с этим у большинства ребят возникают проблемы. Работа вместе с <strong>решебником по алгебре за 10-11 классы авторов Колмогорова, Абрамова, Дудницына</strong> позволит преодолеть все препятствия в учебе. Детально расписанная в пособии информация поможет прекрасно понять материал и научиться применять теорию на практике. </p> <h2> Что представляет собой решебник к учебнику Колмогорова (Просвещение) </h2> <p> Верные ответы — это далеко не все, что содержится во вспомогательном пособии. Сборник с готовыми домашними заданиями структурно и по содержанию полностью копирует учебник под редакцией Колмогорова и включает: </p> <ul> <li>тематические параграфы с соответствующими им упражнениями;</li> <li>номера к разделу «Задачи на повторение»;</li> <li>задачи повышенной трудности.</li> </ul> <p> Каждое решение расписано максимально подробно, с выкладками по теории, графиками и выводами. В особо сложных вопросах авторы дают дополнительные комментарии. Материал изложен простым языком, доступным для понимания абсолютно всем старшеклассникам. Электронный формат существенно облегчает работу с пособием, позволяет выбрать удобный ритм для учебы, экономит время и силы ребенка. </p> <h2> Зачем использовать ГДЗ по алгебре </h2> <p> Даже в выпускном классе нельзя опускать руки, если вдруг освоение алгебры не задалось. Еще есть время поправить свои оценки и знания. Главное правильно распределить свое время, найти верного помощника и вернуть интерес к предмету. Решебник позволит все эти элементы совместить воедино для достижения блестящего результата. Предложенное пособие станет тем консультантом, который даст возможность подростку быстро и качественно выполнить домашнее задание. Это в свою очередь позволит вернуть интерес к предмету и, что немало важно, выкроить ценные часы на отдых. Главное - не прибегать к списыванию готовых решений, ведь простое копирование поможет лишь на время, однако на первой же проверочной в классе обман вскроется. Если обращаться к справочнику для самопроверки и разбора сложных задач, то отличные оценки не заставят себя долго ждать. </p>"

Помимо идеальной подготовки домашних заданий, подросток сможет самостоятельно осваивать новые темы, выполнять диагностику своих знаний и восполнять в них пробелы, повторять и закреплять изученный материал. При этом ребенку не понадобятся дополнительные консультации педагога. Со всеми вопросами и темами текущего учебного года он справится самостоятельно. </p> <h2> Что готовит школьникам алгебра в 10-11 классах </h2> <p> Алгебру можно назвать лидером среди всех учебных дисциплин по количеству изучаемых тем. В десятом и одиннадцатом классах все усложняется тем, что помимо новых разделов, ребятам предстоит огромная работа по повторению ранее пройденного материала, ведь в конце года всех их ждет сложнейшее испытание - итоговый экзамен по предмету. Но его результат будет зависеть от того, насколько хорошо ребята освоят следующие разделы: </p> <ol> <li>Тригонометрические функции.</li> <li>Производная и её применения.</li> <li>Первообразная и интеграл.</li> <li>Показательная и логарифмическая функции.</li> <li>Действительные числа.</li> <li>Функции. </ol> <p> Материал очень насыщенный и достаточно сложный. При этом недостаточно будет просто вызубрить массу формул и правил. Простое заучивание - это лишь часть работы. Главное научиться применять полученные знания на практике. Именно с этим у большинства ребят возникают проблемы.

Решение 5. №553 (с. 259)

а) Для вычисления определенного интеграла $\int_1^7 \frac{2dx}{x}$ воспользуемся формулой Ньютона-Лейбница: $\int_a^b f(x)dx = F(b) - F(a)$, где $F(x)$ — первообразная для $f(x)$.
Сначала вынесем константу за знак интеграла:
$\int_1^7 \frac{2dx}{x} = 2 \int_1^7 \frac{dx}{x}$
Первообразная для функции $f(x) = \frac{1}{x}$ есть $F(x) = \ln|x|$.
Применим формулу Ньютона-Лейбница:
$2 \int_1^7 \frac{dx}{x} = 2 [\ln|x|]_1^7$
На отрезке интегрирования $[1, 7]$ значение $x$ положительно, поэтому $|x| = x$.
$2 [\ln x]_1^7 = 2 (\ln 7 - \ln 1)$
Так как $\ln 1 = 0$, получаем:
$2 (\ln 7 - 0) = 2 \ln 7$.
Ответ: $2 \ln 7$.

б) Вычислим интеграл $\int_{-1}^1 \frac{dx}{3-2x}$.
Найдем первообразную для функции $f(x) = \frac{1}{3-2x}$. Это табличный интеграл вида $\int \frac{dx}{ax+b} = \frac{1}{a}\ln|ax+b|$. В нашем случае $a=-2, b=3$.
Таким образом, первообразная $F(x) = -\frac{1}{2}\ln|3-2x|$.
Применим формулу Ньютона-Лейбница:
$\int_{-1}^1 \frac{dx}{3-2x} = [-\frac{1}{2}\ln|3-2x|]_{-1}^1$
Подставляем верхний и нижний пределы интегрирования:
$[-\frac{1}{2}\ln|3-2(1)|] - [-\frac{1}{2}\ln|3-2(-1)|] = -\frac{1}{2}\ln|3-2| - (-\frac{1}{2}\ln|3+2|)$
$ = -\frac{1}{2}\ln|1| + \frac{1}{2}\ln|5| = -\frac{1}{2}\ln 1 + \frac{1}{2}\ln 5$
Так как $\ln 1 = 0$, получаем:
$0 + \frac{1}{2}\ln 5 = \frac{1}{2}\ln 5$.
Ответ: $\frac{1}{2}\ln 5$.

в) Вычислим интеграл $\int_1^e \frac{dx}{x}$.
Первообразная для подынтегральной функции $f(x) = \frac{1}{x}$ есть $F(x) = \ln|x|$.
Применим формулу Ньютона-Лейбница:
$\int_1^e \frac{dx}{x} = [\ln|x|]_1^e$
На отрезке интегрирования $[1, e]$ значение $x$ положительно, поэтому $|x|=x$.
$[\ln x]_1^e = \ln e - \ln 1$
По определению натурального логарифма $\ln e = 1$, а $\ln 1 = 0$.
$1 - 0 = 1$.
Ответ: $1$.

г) Вычислим интеграл $\int_0^3 \frac{dx}{3x+1}$.
Найдем первообразную для функции $f(x) = \frac{1}{3x+1}$. Используем формулу для интеграла вида $\int \frac{dx}{ax+b} = \frac{1}{a}\ln|ax+b|$. В данном случае $a=3, b=1$.
Первообразная $F(x) = \frac{1}{3}\ln|3x+1|$.
Применим формулу Ньютона-Лейбница:
$\int_0^3 \frac{dx}{3x+1} = [\frac{1}{3}\ln|3x+1|]_0^3$
Подставляем верхний и нижний пределы:
$[\frac{1}{3}\ln|3(3)+1|] - [\frac{1}{3}\ln|3(0)+1|] = \frac{1}{3}\ln|9+1| - \frac{1}{3}\ln|0+1|$
$= \frac{1}{3}\ln|10| - \frac{1}{3}\ln|1| = \frac{1}{3}\ln 10 - \frac{1}{3}\ln 1$
Так как $\ln 1 = 0$, получаем:
$\frac{1}{3}\ln 10 - 0 = \frac{1}{3}\ln 10$.
Ответ: $\frac{1}{3}\ln 10$.
