Draw a picture of an angle that measures radians.

  1. Approximately how many degrees is this?

    Notice that radians . Unit Circle, line segment from center to point in fourth quadrant, center shaded sector, from positive, x axis, to line segment, is labeled  6 radians.
    So it's a little less than .

  2. Using only your picture, estimate the sine of 6 radians.

    Added to diagram, red vertical segment, from end of radius, in fourth quadrant, to positive x axis.
