When Θ = 5 pi over 3, what are the reference angle and the sign values for sine, cosine, and tangent?
Θ'= pi over 3, cosine is positive, sine and tangent are negative
Θ'= 5 pi over 3, sine and cosine are positive, tangent is negative
Θ'= negative pi over 3, sine and cosine are positive, tangent is negative
Θ' = negative 5 pi over 3, cosine is positive, sine and tangent are negative

Best ResponseYou've already chosen the best response.0quadrants of the unit circle dw:1441652942098:dw which quadrant is 5/3 pi in..? then you'll know the signs of the ratios remember if x is the reference angle 2nd quadrant pi  x 3rd quadrant pi + x 4th quadrant 2pi  x hope it helps...
