both values are positive.
is an angle in quadrant IV ... its cosine value is close to 1
is an angle in quadrant I ... its cosine value is close to 1/2
... just a matter of familiarity with the unit circle and radian values of angles.
Refer to the figure, which indicates radian measure on the unit circle for angles in standard position. Determine whether the quantities are positive or negative or zero.
cos 6 + cos 1
and
cos 6 - cos 1
I really don't even know how to start on this one.
Thanks guys
