14.if sinθ = -4/5 and tanθ = -4/3, what is the value of cosθ ?

19. if tanθ = √33/4, use the fundamental identities to find sinθ < 0


please help me

  • math trigono -

    1. cot = 1/tan
    2. sec = 1/cos
    7. tan,cot > 0 in QI,QIII
    14. cos = sin/tan
    19. 4^2 + (√17)^2 = (√33)^2, sin = tan*cos

    so, what are your answers?
