Re: Trigonometria
Sugestão
cos(3.a) = 4.cos³a - 3.cosa ---> Fazendo a = 2.x --->
cos(6.x) = 4.cos³(2.x) - 3.cos(2.x)
sec(2.x) = 1/cos(2.x) ---> cossec(2.x) = 1/sen(2.x)
cos(3.a) = 4.cos³a - 3.cosa ---> Fazendo a = 2.x --->
cos(6.x) = 4.cos³(2.x) - 3.cos(2.x)
sec(2.x) = 1/cos(2.x) ---> cossec(2.x) = 1/sen(2.x)
