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.

а) Для вычисления определенного интеграла $\int_{-1}^{2} x^4 dx$ используется формула Ньютона-Лейбница: $\int_a^b f(x)dx = F(b) - F(a)$, где $F(x)$ — первообразная для функции $f(x)$.

1. Находим первообразную для подынтегральной функции $f(x) = x^4$. Используя табличный интеграл для степенной функции $\int x^n dx = \frac{x^{n+1}}{n+1}$, получаем:

$F(x) = \int x^4 dx = \frac{x^{4+1}}{4+1} = \frac{x^5}{5}$.

2. Применяем формулу Ньютона-Лейбница, подставляя пределы интегрирования $a = -1$ и $b = 2$:

$\int_{-1}^{2} x^4 dx = \left. \frac{x^5}{5} \right|_{-1}^{2} = \frac{2^5}{5} - \frac{(-1)^5}{5}$.

3. Выполняем вычисления:

$\frac{32}{5} - \left(-\frac{1}{5}\right) = \frac{32}{5} + \frac{1}{5} = \frac{33}{5}$.

Ответ: $\frac{33}{5}$.

б) Вычислим интеграл $\int_{0}^{\frac{\pi}{2}} \cos x dx$.

1. Первообразная для функции $f(x) = \cos x$ — это $F(x) = \sin x$, так как $(\sin x)' = \cos x$.

2. Применяем формулу Ньютона-Лейбница:

$\int_{0}^{\frac{\pi}{2}} \cos x dx = \left. \sin x \right|_{0}^{\frac{\pi}{2}} = \sin\left(\frac{\pi}{2}\right) - \sin(0)$.

3. Подставляем значения тригонометрических функций:

$\sin\left(\frac{\pi}{2}\right) = 1$

$\sin(0) = 0$

4. Находим результат:

$1 - 0 = 1$.

Ответ: 1.

в) Вычислим интеграл $\int_{1}^{3} x^3 dx$.

1. Находим первообразную для функции $f(x) = x^3$:

$F(x) = \int x^3 dx = \frac{x^{3+1}}{3+1} = \frac{x^4}{4}$.

2. Применяем формулу Ньютона-Лейбница:

$\int_{1}^{3} x^3 dx = \left. \frac{x^4}{4} \right|_{1}^{3} = \frac{3^4}{4} - \frac{1^4}{4}$.

3. Выполняем вычисления:

$\frac{81}{4} - \frac{1}{4} = \frac{80}{4} = 20$.

Ответ: 20.

г) Вычислим интеграл $\int_{0}^{\frac{\pi}{4}} \frac{dx}{\cos^2 x}$.

1. Первообразная для функции $f(x) = \frac{1}{\cos^2 x}$ — это $F(x) = \tan x$, поскольку $(\tan x)' = \frac{1}{\cos^2 x}$.

2. Применяем формулу Ньютона-Лейбница:

$\int_{0}^{\frac{\pi}{4}} \frac{dx}{\cos^2 x} = \left. \tan x \right|_{0}^{\frac{\pi}{4}} = \tan\left(\frac{\pi}{4}\right) - \tan(0)$.

3. Подставляем значения тангенса:

$\tan\left(\frac{\pi}{4}\right) = 1$

$\tan(0) = 0$

4. Находим результат:

$1 - 0 = 1$.

Ответ: 1.
