Question 1072254
{{{csc^5(x)-4csc(x)=0}}}
{{{csc(x)(csc^4(x)-4)=0}}}
{{{highlight_green(csc(x)(csc^2(x)-2)(csc^2(x)+2)=0)}}}
-



At least one of the factors must be 0.


{{{csc(x)=1/sin(x)=0}}}, not useful; not possible.



{{{csc^2(x)-2=0}}}
{{{csc^2(x)=2}}}
{{{1/(sin^2(x))=2}}}
{{{sin^2(x)=1/2}}}
{{{sin(x)=0+- sqrt(2)/2}}}
{{{system(x=45*degrees,or,x=135*degrees)}}}
or

{{{system(x=225*degree,or,x=315)}}}
