1) $-4sin( \frac{ \pi }{3} +a)-2sina=-4(sin \frac{ \pi }{3} cosa+sinacos \frac{ \pi }{3} )-2sina=\\
=- 2 \sqrt{3} cosa-2sina-2sina=- 2 \sqrt{3} cosa-4sina$

2) $4sin( \frac{ \pi }{3} +a)-2sina=4(sin \frac{ \pi }{3} cosa+sinacos \frac{ \pi }{3} )-2sina=\\
=2 \sqrt{3} cosa + 2sina-2sina=2 \sqrt{3} cosa$
