Question 1181371


{{{(cos(theta )+ sin( theta) )(1-2sin (theta))=0}}}

if {{{cos(theta )+ sin( theta) =0}}}

 =>{{{cos(theta )=- sin( theta)  }}}

{{{theta  =3pi/4+pi*n}}}, {{{n }}}element {{{Z}}}


if {{{1-2sin (theta)=0}}}
=>{{{1=2sin (theta)}}}
=>{{{1/2=sin (theta)}}}

{{{theta=sin^-1 (1/2)}}}
{{{theta=pi/6}}}
