Углы в радианах составляют: 30=π630 raised to the composed with power equals the fraction with numerator bold pi and denominator 6 end-fraction , 45=π445 raised to the composed with power equals the fraction with numerator bold pi and denominator 4 end-fraction , 60=π360 raised to the composed with power equals the fraction with numerator bold pi and denominator 3 end-fraction , 90=π290 raised to the composed with power equals the fraction with numerator bold pi and denominator 2 end-fraction , 180=π180 raised to the composed with power equals bold pi, 270=3π2270 raised to the composed with power equals the fraction with numerator 3 bold pi and denominator 2 end-fraction и 360=2π360 raised to the composed with power equals 2 bold pi. Шаг 1: Определение формулы перехода Для перевода величины угла из градусной меры в радианную используется базовая связь: развернутый угол 180180 raised to the composed with power равен πpi радиан. Из этого следует формула: αrad=αdegπ180alpha sub r a d end-sub equals alpha sub d e g end-sub center dot the fraction with numerator pi and denominator 180 end-fraction где αdegalpha sub d e g end-sub — угол в градусах, а αradalpha sub r a d end-sub — искомый угол в радианах. Шаг 2: Расчет значений для каждого угла Применим формулу к заданным значениям, сокращая полученные дроби:

  1. Для 3030 raised to the composed with power: 30π180=30π180=π630 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 30 pi and denominator 180 end-fraction equals the fraction with numerator pi and denominator 6 end-fraction Для 4545 raised to the composed with power: 45π180=45π180=π445 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 45 pi and denominator 180 end-fraction equals the fraction with numerator pi and denominator 4 end-fraction Для 6060 raised to the composed with power: 60π180=60π180=π360 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 60 pi and denominator 180 end-fraction equals the fraction with numerator pi and denominator 3 end-fraction Для 9090 raised to the composed with power: 90π180=90π180=π290 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 90 pi and denominator 180 end-fraction equals the fraction with numerator pi and denominator 2 end-fraction Для 180180 raised to the composed with power: 180π180=π180 center dot the fraction with numerator pi and denominator 180 end-fraction equals pi Для 270270 raised to the composed with power: 270π180=270π180=3π2270 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 270 pi and denominator 180 end-fraction equals the fraction with numerator 3 pi and denominator 2 end-fraction Для 360360 raised to the composed with power: 360π180=360π180=2π360 center dot the fraction with numerator pi and denominator 180 end-fraction equals the fraction with numerator 360 pi and denominator 180 end-fraction equals 2 pi
