Question 797740
They are telling you that the angle is in the 3rd quadrant
so what you have is {{{ tan( theta ) = (-1)/(-3) }}}
{{{ sqrt( (-1)^2 + (-3)^2 ) = sqrt( 10 ) }}}
---------------
{{{ sin ( theta ) = (-1) / sqrt(10) }}}
{{{ cos( theta ) = (-3) / sqrt(10) }}}
{{{ cot( theta ) = (-3) / (-1) }}}
You can finish this
