Question

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
