Find two solutions of each equation.
Give your answers in degrees
(0° ≤ θ < 360°)
cos(t) = 1/2
t = 60 or t = 300
--------------------------
and in radians(0 ≤ θ < 2π).
cos θ = 1/2
t = pi/3 or t = (5/6)pi

The adjacent side is
The rotating vector is
The opposite side is ,
so degrees
and
This is with in the 1st quadrant
--------------------------------------
could also be in the 4th quadrant
The adjacent side is
The rotating vector is
The opposite side is ,
degrees
and
---------------------------
In the the other 2 quadrants, 2nd and 3rd,
the cos is negative
