Radian Measure and Reference Angles

  • Points on Unit Circle
    • Given the abscissa of the point, determine the appropriate ordinate for a given quadrant
    • Given an angle in degrees or radians, determine the corresponding point on the unit circle
    • Given coordinates for a given angle, determine appropriate points for angle + pi, angle - pi and -angle
  • Radian Measure
    • Relate pictures of radians between 1 rad and 6 rad to the precise measure
    • Determine coterminal angles
    • Convert degrees to radians
    • Convert radians to degrees
    • Evaluate trig functions at nice angles but given in radians
  • Reference Angles
    • Given nice angles in degrees or radians, determine a corresponding reference angle
    • Given angles with integral radian values, determine reference angles
