sin (x + PI/3) = cos (x – PI/3). Solve for x. Hi Could someone please help me solve the above question? For some reason I can't seem to get x. I end up with: sin x + root(3) cos x = cos x + root(3) sin x

Hello, Originally Posted by xwrathbringerx sin (x + PI/3) = cos (x – PI/3). Solve for x. Hi Could someone please help me solve the above question? For some reason I can't seem to get x. I end up with: sin x + root(3) cos x = cos x + root(3) sin x A way to solve is to note that Then can be transformed into Then, two possibilities : - use the trigonometric identity - or recall that (you can easily see that on a unit circle)
