sec x = 1 / cos x

cos sec x = 1 / sen x

cot gx = cos x / sen x = 1 / tg x

sen^2 x + cos^2 x = 1

sec^2 x = 1 + tg^2 x

Determine, respectivamente, a cotangente dos arcos de 45° e 60°.

Acerca do resultado, assinale a alternativa CORRETA: A) cotg 45° = 1/2 e cotg 60° = 3/4. B) cotg 45° = 1 e cotg 60° = -1. C) cotg 45° = 3 e cotg 60° = raiz quadrada de 3. D) cotg 45° = 1 e cotg 60° = raiz quadrada de 3 sobre 3.
