3. First factor as a difference of cubes:
For the remaining group, apply the double angle identity.
5. seems rather tricky. You might want to post another question for that problem alone...
6. Factorize the left side as a sum of cubes:
From here we have to prove that
We can write everything in terms of sine:
(double angle identity)
(angle sum identity)
After some simplifying, we're left with showing that
or
This last equality follows from what you could the triple angle identity for sine,
