If sin(x) = , what is sin(x) ?

Solve for x . 2 sin(x)cos(x) = 1 .

Solve for x . sin(x) - = cos(x) .

Solve for x . cos(x)tan(x) + 1 = sec2(x) - tan2(x) - 1 .

Solve for x . 2 cos(x) = sin(x)csc(x) .

Solve for x . sin(x)tan(x)sec(x) = .

Solve for x . = sin2(x) + cos2(x) - sin(x)csc(x) .

Solve for x . tan(x)sin(x)cos(x) = sin(x)sec(x) .

Solve for x . 2 cos(x) = - (csc2(x) - )
