Question

Помогите преобразовать tg85+ctg85

Answer 1

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
