Для перевода величин используются формулы перехода между градусной и радианной мерами угла. В радианах: 30=π630 raised to the composed with power equals the fraction with numerator pi and denominator 6 end-fraction , 45=π445 raised to the composed with power equals the fraction with numerator pi and denominator 4 end-fraction , 315=7π4315 raised to the composed with power equals the fraction with numerator 7 pi and denominator 4 end-fraction , 1000=50π91000 raised to the composed with power equals the fraction with numerator 50 pi and denominator 9 end-fraction . В градусах: 5π36=25the fraction with numerator 5 pi and denominator 36 end-fraction equals 25 raised to the composed with power , 7π12=105the fraction with numerator 7 pi and denominator 12 end-fraction equals 105 raised to the composed with power , 4π3=240the fraction with numerator 4 pi and denominator 3 end-fraction equals 240 raised to the composed with power . ️ Шаг 1: Перевод из градусов в радианы Для перевода угла из градусов в радианы используется формула αрад=απ180alpha sub р а д end-sub equals alpha raised to the composed with power center dot the fraction with numerator pi and denominator 180 raised to the composed with power end-fraction . Применяем её к заданным значениям:

  1. 30π180=30π180=π630 raised to the composed with power center dot the fraction with numerator pi and denominator 180 raised to the composed with power end-fraction equals the fraction with numerator 30 pi and denominator 180 end-fraction equals the fraction with numerator bold pi and denominator 6 end-fraction 45π180=45π180=π445 raised to the composed with power center dot the fraction with numerator pi and denominator 180 raised to the composed with power end-fraction equals the fraction with numerator 45 pi and denominator 180 end-fraction equals the fraction with numerator bold pi and denominator 4 end-fraction 315π180=315π180=7π4=1,75π315 raised to the composed with power center dot the fraction with numerator pi and denominator 180 raised to the composed with power end-fraction equals the fraction with numerator 315 pi and denominator 180 end-fraction equals the fraction with numerator 7 pi and denominator 4 end-fraction equals 1 comma 75 bold pi 1000π180=1000π180=50π91000 raised to the composed with power center dot the fraction with numerator pi and denominator 180 raised to the composed with power end-fraction equals the fraction with numerator 1000 pi and denominator 180 end-fraction equals the fraction with numerator 50 bold pi and denominator 9 end-fraction

️ Шаг 2: Перевод из радианов в градусы Для перевода угла из радианов в градусы используется формула α=αрад180πalpha raised to the composed with power equals alpha sub р а д end-sub center dot the fraction with numerator 180 raised to the composed with power and denominator pi end-fraction . Подставляем значения:

  1. 5π36180π=518036=55=25the fraction with numerator 5 pi and denominator 36 end-fraction center dot the fraction with numerator 180 raised to the composed with power and denominator pi end-fraction equals the fraction with numerator 5 center dot 180 and denominator 36 end-fraction equals 5 center dot 5 equals 25 raised to the composed with power 7π12180π=718012=715=105the fraction with numerator 7 pi and denominator 12 end-fraction center dot the fraction with numerator 180 raised to the composed with power and denominator pi end-fraction equals the fraction with numerator 7 center dot 180 and denominator 12 end-fraction equals 7 center dot 15 equals 105 raised to the composed with power 4π3180π=41803=460=240the fraction with numerator 4 pi and denominator 3 end-fraction center dot the fraction with numerator 180 raised to the composed with power and denominator pi end-fraction equals the fraction with numerator 4 center dot 180 and denominator 3 end-fraction equals 4 center dot 60 equals 240 raised to the composed with power

Ответ:

  1. Радианы: π6the fraction with numerator pi and denominator 6 end-fraction , π4the fraction with numerator pi and denominator 4 end-fraction , 7π4the fraction with numerator 7 pi and denominator 4 end-fraction , 50π9the fraction with numerator 50 pi and denominator 9 end-fraction .
  2. Градусы: 2525 raised to the composed with power, 105105 raised to the composed with power, 240240 raised to the composed with power.

Нужно ли выполнить дополнительные преобразования (например, выделить целую часть или перевести в десятичные дроби) для этих значений?
