Find all the exact t-values for each which are solutions for the following:
1) Sin(t)= Square root of -3/2
t is in QIII or QIV::
Reference agle:: t = 60 degrees or pi/3
t = 180+60 = 240 deg. or t = 360-60 = 300 deg.
====================================================
2) Cos(t)= 1
t = 0 degrees
------------------------
3) Sin(t)= -0.5
t is in QIII or QIV
Reference angle:: 30 deg or pi/6
t = 180+30 = 210 deg or t = 360-30 = 330 deg
====================================================
