Sendo sen x= -3/5 e π < x < 3π/2, calcule:? ... Pedem-se várias funções trigonométricas,sabendo-se que senx = -3/5 e que "x' está no seguinte intervalo: PI < x < 3PI/2 ---Veja que esse ... cosx = +-4/5 -----mas, como no 3º quadrante o cosseno é negativo, então temos que: .... Se cos x = 3/5 e 3π/2 < x < 2π , calcular sen(3x)?.
