    BASIC Grade 11 Trigonometry Question on tan, cosec, sec, cot

    The question I don't get is:

    "For which of the trigonometric points defined in the previous question is it impossible to calculate:

    a) the tangent?
    b) the cosecant?
    c) the secant?
    d) the cotangent?"

    the previous question was:

    "Without using a calculator, give the coordinats of the trigonometric point corresponding to a central angle that measures"

    a) 0
    b) -90
    c) 180
    d) -270
    e) -360"

    Any help would be GREATLY appreciated!
    Thanks!

    Go ahead and calculate them all at those locations. Which ones have a zero in the bottom and are thus impossible to calculate?
