(-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"
