There is no AutoIt answer for this, more of a "Chat" area.

You need to use Trigonometric Identities to reduce the equation into something that equals 1/2.

ie:

cos0 - sin30 = 1/2

I didn't actually work out the equation but used GraphCalc to solve it.

$x = 1.1780972
$eq = cos($x) * cos(2*$x) * cos(3*$x) - sin($x) * sin(2*$x) * sin(3*$x)
msgbox(0,'',$eq)
