Помогите преобразовать tg85+ctg85

tan(85)=(sin(85)/cos(85)) ctg(85)=(cos(85)/sin(85)) sin(85)=0.996194698091746 cos(85)=0.0871557427476582 sin(85)/cos(85)+ctg(85) sin(85)/cos(85)+cos(85)/sin(85) 0.996194698091746/0.0871557427476582≈11.4300523027613 0.0871557427476582/0.996194698091746≈0.087488663525924 11.4300523027613+0.087488663525924=11.5175409662872
