Question 1179524
<pre>

{{{2sin^2(x) + 3 cos(x)=3}}}

{{{2(1-cos^2(x)^"") + 3cos(x)=3}}}

{{{2-2cos^2(x) + 3cos(x)=3}}}

{{{-2cos^2(x) + 3cos(x)-1=0}}}

{{{2cos^2(x) - 3cos(x)+1=0}}}

{{{(2cos(x)-1^"")(cos(x)-1^"")=0}}}

{{{2cos(x)-1=0}}};  {{{cos(x)-1=0}}}

{{{2cos(x)=1}}};    {{{cos(x)=1}}}

{{{cos(x)=1/2}}}

{{{x = matrix(1,3,pi/3,",",5pi/3)}}},  {{{x=0}}}
