Cos3A+Cos3B+Cos3C=-1-4Cos3A/2.Cos3B/2.Sin3C/2

This video is basically prepared for SEE students for the subject optional maths. The video may have some weakness. I would be very grateful to any suggestions and recommendations from the viewers. Also this might not be suitable for those students who do not have idea of basic arithmetic and algebraic calculations.
This video provides best view if you enhance the quality to 1020p or 720p and watch in landscape. Also using headphones provides you better sound.
Thank You
