Question 4(multiple choice worth 2 points) (05.05 mc) if cos θ = square root 2 over 2 and 3 pi over 2 < θ < 2π, what are the values of sin θ and tan θ? sin θ = square root 2 over 2; tan θ = −1 sin θ = negative square root 2 over 2; tan θ = 1 sin θ = square root 2 over 2; tan θ = negative square root 2 sin θ = negative square root 2 over 2; tan θ = −1
