What are the sine, cosine, and tangent of 5 pi over 3 radians? (1 point) sin θ = negative square root 3 over 2 ; cos θ = 1 over 2 ; tan θ = negative square root three sin θ = square root 3 over 2 ; cos θ = negative 1 over 2 ; tan θ = square root three sin θ = square root 3 over 2 ; cos θ = 1 over 2 ; tan θ = square root three

The angle 5pi/3 is in the fourth quadrant (meaning cosine is positive while sine & tangent are negative), and its reference angle is 60 degrees with respect to the horizontal. Therefore its sine is -sqrt(3)/2, its cosine is 1/2, and its tangent is -sqrt(3). This is the first choice.
