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. №342 (с. 183)

а) Общий вид первообразных для функции $f(x)$ находится путем вычисления неопределенного интеграла $\int f(x)dx$. Данная функция: $f(x) = 2 - x^3 + \frac{1}{x^3}$.
Представим функцию в виде, удобном для интегрирования: $f(x) = 2 - x^3 + x^{-3}$.
Найдем первообразную $F(x)$, используя правила интегрирования (интеграл суммы равен сумме интегралов):
$F(x) = \int (2 - x^3 + x^{-3})dx = \int 2dx - \int x^3dx + \int x^{-3}dx$.
Используем формулу для интегрирования степенной функции $\int x^n dx = \frac{x^{n+1}}{n+1} + C$ и константы $\int k dx = kx + C$:
$\int 2dx = 2x$
$\int x^3dx = \frac{x^{3+1}}{3+1} = \frac{x^4}{4}$
$\int x^{-3}dx = \frac{x^{-3+1}}{-3+1} = \frac{x^{-2}}{-2} = -\frac{1}{2x^2}$
Суммируя полученные результаты и добавляя произвольную постоянную $C$, получаем общий вид первообразных:
$F(x) = 2x - \frac{x^4}{4} - \frac{1}{2x^2} + C$.
Ответ: $F(x) = 2x - \frac{x^4}{4} - \frac{1}{2x^2} + C$.

б) Дана функция $f(x) = x - \frac{2}{x^5} + \cos x$.
Представим функцию в виде: $f(x) = x - 2x^{-5} + \cos x$.
Найдем общий вид первообразных $F(x)$:
$F(x) = \int (x - 2x^{-5} + \cos x)dx = \int x dx - \int 2x^{-5}dx + \int \cos x dx$.
Интегрируем каждое слагаемое по отдельности:
$\int x dx = \frac{x^{1+1}}{1+1} = \frac{x^2}{2}$
$\int 2x^{-5}dx = 2 \cdot \int x^{-5}dx = 2 \cdot \frac{x^{-5+1}}{-5+1} = 2 \cdot \frac{x^{-4}}{-4} = -\frac{x^{-4}}{2} = -\frac{1}{2x^4}$
$\int \cos x dx = \sin x$
Складываем результаты и добавляем константу $C$:
$F(x) = \frac{x^2}{2} - (-\frac{1}{2x^4}) + \sin x + C = \frac{x^2}{2} + \frac{1}{2x^4} + \sin x + C$.
Ответ: $F(x) = \frac{x^2}{2} + \frac{1}{2x^4} + \sin x + C$.

в) Дана функция $f(x) = \frac{1}{x^2} - \sin x$.
Представим функцию в виде: $f(x) = x^{-2} - \sin x$.
Найдем общий вид первообразных $F(x)$:
$F(x) = \int (x^{-2} - \sin x)dx = \int x^{-2}dx - \int \sin x dx$.
Интегрируем каждое слагаемое:
$\int x^{-2}dx = \frac{x^{-2+1}}{-2+1} = \frac{x^{-1}}{-1} = -\frac{1}{x}$
$\int \sin x dx = -\cos x$
Складываем результаты и добавляем константу $C$:
$F(x) = -\frac{1}{x} - (-\cos x) + C = -\frac{1}{x} + \cos x + C$.
Ответ: $F(x) = -\frac{1}{x} + \cos x + C$.

г) Дана функция $f(x) = 5x^2 - 1$.
Найдем общий вид первообразных $F(x)$:
$F(x) = \int (5x^2 - 1)dx = \int 5x^2dx - \int 1dx$.
Интегрируем каждое слагаемое:
$\int 5x^2dx = 5 \cdot \int x^2dx = 5 \cdot \frac{x^{2+1}}{2+1} = 5 \cdot \frac{x^3}{3} = \frac{5x^3}{3}$
$\int 1dx = x$
Складываем результаты и добавляем константу $C$:
$F(x) = \frac{5x^3}{3} - x + C$.
Ответ: $F(x) = \frac{5x^3}{3} - x + C$.
