Question 951033
{{{2 - 2*cos^2(x) - sqrt(2)*sin(x) = 0}}}
{{{cos^2(x) = 1 - sin^2(x)}}}
-----
{{{2 - 2*(1 - sin^2(x)) - sqrt(2)*sin(x) = 0}}}
{{{2 - 2 + 2sin^2(x) - sqrt(2)*sin(x) = 0}}}
{{{2sin^2(x) - sqrt(2)*sin(x) = 0}}}
{{{sin(x)*(2sin(x) - sqrt(2)) = 0}}}
sin(x) = 0
x = 0, pi, 2pi, etc
=================
2sin(x) - sqrt(2) = 0
sin(x) = sqrt(2)/2
x = pi/4, 3pi/4, etc
