Question 562207
{{{ tan((17/12)*pi ) }}}
Note that {{{ (12/12)*pi = pi }}}
so, {{{ (17/12)*pi = pi + (5/12)*pi }}}
-----------
This is an angle in the 3rd quadrant
where the tangent is (-)/(-), which
is positive.
-----------
{{{ pi/3 = 60 }}} degrees
{{{ pi/6 = 30 }}} degrees
{{{ pi/12 = 15 }}} degrees
{{{ (5/12)*pi = 75 }}} degrees
-----------
 {{{ tan( (17/12)*pi) = tan( (5/12)*pi) }}} answer
