Question

Determine o valor de sec x + csc x / 1+ tanx sabendo que sen x = 1/2

Answer 1

Resposta:

2

Explicação passo-a-passo:

(Sec x + csc x)/1+tan x

(1/Cos x + 1/Sen x) /. 1+senx/cos x

(1/Cos x + 1/Sen x) /. 1 +½/cos x

(1/Cos x + 1/½) / 1+ 1/2cos x

(1/Cos x + 2) /. 1+ 1/2Cos x

(1+2cos x/Cos x) / 1+ 2Cos x/2cos x

1+2cos x/Cos x * 2cos x / 1+ 2Cos x

2 Cos x/cos x
