01) Sendo cos x = 5 / 13 e x ∈ quarto quadrante, calcule a cossec x *
02) Dado que cos x = 3 / 5, cotg x = 3 / 4 e que x pertence o primeiro quadrante, calcule o sen x. *
03) O cos x = - 12 / 13, e x está no terceiro quadrante, sendo assim, determine o valor que a tg x pode assumir. *
04) Simplifique a expressão (tg² x ) / (1 + tg² x) *
