(sin²30+tg²60)/(2·cos60)=(½)²+(√3/2)² / (2·½)= (¼+³/₄)/1 =4/4 =1
(cos²30+ctg²60)/(√3sin60)= (√3/2)²+(√3/3)² /(√3·√3/2 )= (³/₄+³/₉)/(³/₂)=(³/₄+⅓)/(³/₂)=
(⁹/₁₂+⁴/₁₂)/ (³/₂)=¹³/₁₂ · ⅔ =²⁶/₃₆ =¹³/₁₈
(sin²60+tg²30)/(2·tg45)=(√3/2)²+√3/3)²/ (2·1)=(¾ +⅓)/2 =(9/12 +4/12)/2=13/12· 1/2 =13/24
(cos²60+ctg²30)/(√3·ctg60)=(½)²+(√3)² / (√3·√3/3) =(¼+3)/1 =3¼
