Question

What are the sine, cosine, and tangent of Θ = 7 pi over 4 radians?

sin Θ = negative square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = 1
sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = 1
sin Θ = square root 2 over 2; cos Θ = negative square root 2 over 2 tan Θ = −1
sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = −1

Answer 1

uh oh, was I wrong? or is this a different question?

Answer 2

No, I forgot how to do it XD

Answer 3

Oh, No! I read it wrong. I am so sorry. The correct answer should be sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = −.
