Здравствуйте, Виктор!
Действительно, при разложении заданной функции в ряд Фурье возникают определённые сложности, связанные с громоздкостью промежуточных вычислений. Поэтому я в меру своих возможностей оказываю Вам помощь и излагаю вкратце ход выполнения задания ниже. Для вычисления интегралов я использовал этот калькулятор: Ссылка >>.
График заданной функции показан в прикреплённом файле. Эта функция нечётная, потому что
Значит, её ряд Фурье имеет вид
где
В рассматриваемом случае
Следовательно, при
