a=cotg 60°+sen 60°-cossec 60°
Soluções para a tarefa
Respondido por

cotg 60 = 1/sen 60 = 1/√3/2 = 2/√3 = 2√3/3
sen 60 = √3/2
cossec 60 = cos 60 / sen 60 = 1/2 / √3/2 = 1/√3 = √3/3
2√3/3 + √3/2 - √3/3 =
4√3/6 + 3√3/6 - 2√3/6 =
5√3/6
sen 60 = √3/2
cossec 60 = cos 60 / sen 60 = 1/2 / √3/2 = 1/√3 = √3/3
2√3/3 + √3/2 - √3/3 =
4√3/6 + 3√3/6 - 2√3/6 =
5√3/6
