What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?
a. sin Θ = square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = -1
b. sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = 1
c. sin Θ = square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = 1
d. sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = -1
