Угол 4545 raised to the composed with power находится в первой четверти, углы 175175 raised to the composed with power и 9191 raised to the composed with power — во второй, а угол 355355 raised to the composed with power (указанный дважды) — в четвертой. Шаг 1: Определение границ координатных четвертей Для определения положения угла αalpha на координатной плоскости используются следующие стандартные интервалы:

  • I четверть: 0<α<900 raised to the composed with power is less than alpha is less than 90 raised to the composed with power II четверть: 90<α<18090 raised to the composed with power is less than alpha is less than 180 raised to the composed with power III четверть: 180<α<270180 raised to the composed with power is less than alpha is less than 270 raised to the composed with power IV четверть: 270<α<360270 raised to the composed with power is less than alpha is less than 360 raised to the composed with power

Шаг 2: Распределение заданных углов по интервалам Сравним каждое значение с установленными границами:

  1. 4545 raised to the composed with power: так как 0<45<900 raised to the composed with power is less than 45 raised to the composed with power is less than 90 raised to the composed with power, это I четверть. 175175 raised to the composed with power: так как 90<175<18090 raised to the composed with power is less than 175 raised to the composed with power is less than 180 raised to the composed with power, это II четверть. 355355 raised to the composed with power: так как 270<355<360270 raised to the composed with power is less than 355 raised to the composed with power is less than 360 raised to the composed with power, это IV четверть. 9191 raised to the composed with power: так как 90<91<18090 raised to the composed with power is less than 91 raised to the composed with power is less than 180 raised to the composed with power, это II четверть. 355355 raised to the composed with power: (повтор) так как 270<355<360270 raised to the composed with power is less than 355 raised to the composed with power is less than 360 raised to the composed with power, это IV четверть.

Ответ: I четверть: 4545 raised to the composed with power II четверть: 175,91175 raised to the composed with power comma 91 raised to the composed with power IV четверть: 355,355355 raised to the composed with power comma 355 raised to the composed with power Хотите узнать, как определять четверть для отрицательных углов или значений, превышающих 360 градусов?
