Question 1048504
The angle whose sin is {{{ 1/2 }}} is {{{ pi/6 }}}
In the interval [ 0, {{{pi}}} ], the angle is:
{{{ pi/6 }}}, {{{ 5*pi/6 }}}
-------------------------
For the angle {{{ pi/6 }}}:
{{{ 2x + pi/3 = pi/6 }}}
{{{ 2x = -pi/6 }}}
{{{ x = -pi/12 }}}
-------------------------
For the angle {{{ 5*pi/6 }}},
{{{ 2x + pi/3 = 5*pi/6 }}}
{{{ 2x = 3*pi/6 }}}
{{{ 2x = pi/2 }}}
{{{ x = pi/4 }}}
----------------
