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.

  • Calculus -

    (-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"
