zxzxzx Posted January 3, 2008 Share Posted January 3, 2008 (edited) I have a this mathematical article. cosx * cos2x * cos3x - sinx * sin2x * sin3x = 1/2 How to do this mathematical article in AutoIT ? Help me, please I want to find x x = ? Edited January 3, 2008 by zxzxzx Link to comment Share on other sites More sharing options...
WolfWorld Posted January 3, 2008 Share Posted January 3, 2008 $x = 5 msgbox(0,'',cos($x) * cos(2*$x) * cos(3*$x) - sin($x) * sin(2*$x) * sin(3*$x) * 2) That's it Main project - Eat Spaghetti - Obfuscate and Optimize your script.

weaponx Posted January 3, 2008 Share Posted January 3, 2008 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 = 1/2I 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) Link to comment Share on other sites More sharing options...
