Answer 4

im gonna flip u all over

Answer 5

yes its good

Answer 6

Another way to reach the same conclusion: use the half angle identity:
\[\sin^2x=\frac{1-\cos2x}{2}\\\\
\cos^2x=\frac{1+\cos2x}{2}\]

Answer 7

You could apply the wronskian as well, right?

Answer 8

You could, but those derivatives might make solving the resultant equation tricky. The half-angle identities would make differentiation much easier.

Answer 9

Thanks everyone for the help it is much appreciated
