Find trig function values

Explanation:

Use trig unit circle and trig table of special arcs -->
#sin ((19pi)/3) = sin (pi/3 + 6pi) = sin (pi/3) = sqrt3/2#
#cos ((19pi)/3) = cos (pi/3) = 1/2#
t#an ((19pi)/3) = sin/(cos) = sqrt3#
#cot ((19pi)/3) = 1/(tan) = 1/sqrt3 = sqrt3/3#
#sec ((19pi)/3) = 1/(cos) = 2#
#csc ((19pi)/3) = 1/(sin) = 2/sqrt3 = (2sqrt3)/3#
