Find the reference number and the terminal point determined by t.
a. t = - 7(pi)/6

  • Trig -

    t = -7(pi)/6.
    -7(pi)/6 * 180/(pi) = -210 deg.
    -210 is 210 deg CW from the + x-axis
    and is in the 2nd quadrant.

    Ar = [-210] - 180,
    Ar = 210 - 180 = 30 deg.

    A = 180 - 30 = 150 DEG CW FROM +X AXIS.
