Question

Calcule o valor de E=cos1500+sen35π/6+cos19π/3

Answer 1

Resposta:

cos 1500 --> 1500/360 = 4 e sobram 60 --> cos 60 = 1/2

sen 37pi/6 = sen pi/6 = sen 180/6 = sen 30 = 1/2

cos 19pi/3 = cos pi/3 = cos 180/3 = cos 60 = 1/2

1/2 + 1/2 + 1/2 = 3/2

Answer 2

Resposta:

cos 1500 --> 1500/360 = 4 e sobram 60 --> cos 60 = 1/2

sen 37pi/6 = sen pi/6 = sen 180/6 = sen 30 = 1/2

cos 19pi/3 = cos pi/3 = cos 180/3 = cos 60 = 1/2

1/2 + 1/2 + 1/2 = 3/2
