The point A(3, 5) is one the terminal arm of an angle feta. Determine the exact expressions for the primary trigonmetric ratios for the angle. Would that be 225 degrees.
2V2?

(3,5) is in quadrant III
draw the triangle in that quad, the hypotenuse would be √34
sinØ = 5/√34 , csc Ø = =√34/5
cosØ = 3/√34 , secØ = √34/3
tanØ = 5/3, cotØ = 3/5
"feta" is not a Greek letter but it is a Greek cheese, however "theta" is a Greek letter.
If you listen carefully, your teacher more than likely is saying "Theta"
