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.

Точка движется прямолинейно с ускорением $a(t) = 12t^2 + 4$. Найдите закон движения точки, если в момент $t = 1 \text{ с}$ ее скорость равна $10 \text{ м/с}$, а координата равна $12$ (единица измерения $a$ равна $1 \text{ м/с}^2$).

Решение 5. №350 (с. 184)

Закон движения точки — это функция зависимости ее координаты $x$ от времени $t$, то есть $x(t)$. Чтобы найти эту функцию, необходимо дважды проинтегрировать заданную функцию ускорения $a(t)$, используя начальные условия для определения констант интегрирования.

Шаг 1: Нахождение функции скорости $v(t)$

Скорость $v(t)$ является первообразной для ускорения $a(t)$, то есть $v(t) = \int a(t) dt$. Интегрируем заданную функцию ускорения $a(t) = 12t^2 + 4$:

$v(t) = \int (12t^2 + 4) dt = 12 \cdot \frac{t^3}{3} + 4t + C_1 = 4t^3 + 4t + C_1$

Здесь $C_1$ — постоянная интегрирования. Чтобы найти ее значение, воспользуемся условием, что в момент времени $t = 1$ с скорость $v(1) = 10$ м/с.

Подставляем $t=1$ и $v(1)=10$ в полученное уравнение для скорости:

$10 = 4(1)^3 + 4(1) + C_1$

$10 = 4 + 4 + C_1$

$10 = 8 + C_1$

$C_1 = 2$

Таким образом, функция скорости имеет вид:

$v(t) = 4t^3 + 4t + 2$

Шаг 2: Нахождение закона движения $x(t)$

Координата $x(t)$ (закон движения) является первообразной для скорости $v(t)$, то есть $x(t) = \int v(t) dt$. Интегрируем найденную функцию скорости $v(t) = 4t^3 + 4t + 2$:

$x(t) = \int (4t^3 + 4t + 2) dt = 4 \cdot \frac{t^4}{4} + 4 \cdot \frac{t^2}{2} + 2t + C_2 = t^4 + 2t^2 + 2t + C_2$

Здесь $C_2$ — вторая постоянная интегрирования. Для ее нахождения используем условие, что в момент времени $t = 1$ с координата $x(1) = 12$.

Подставляем $t=1$ и $x(1)=12$ в уравнение для координаты:

$12 = (1)^4 + 2(1)^2 + 2(1) + C_2$

$12 = 1 + 2 + 2 + C_2$

$12 = 5 + C_2$

$C_2 = 7$

Подставив значение $C_2$, получаем искомый закон движения точки:

$x(t) = t^4 + 2t^2 + 2t + 7$

Ответ: $x(t) = t^4 + 2t^2 + 2t + 7$.
