Notice that cos 2 ( x ) : = ( cos ( x ) ) 2 is not the same thing as cos ( 2 x ) . It is indeed true that sin 2 ( x ) = 1 − cos 2 ( x ) and that sin 2 ( x ) = 2 1 − c o s ( 2 x ) . The answer is = 1 2 sin 6 x + 6 x + C Explanation: We use cos 2 x = 2 cos 2 x − 1 Adapting this cos 6 x = 2 cos 2 (3 x) − 1 My second attempt at an actual in class video. This one was way harder to edit and I'm not sure how I feel about it.For more math shorts go to www.MathByFive sin 2 (x) + cos 2 (x) = 1.
