The question discussed in the video: If sin(A/3) = 1/2(a + 1/a), prove sinA = -1/2(a³ + 1/a³)

Dibas, teacher and creator of the SEE Ko Guide, is walking through the solution of trigonometry questions related to the sub-multiples. It is a long question that has appeared on the SEE (Secondary Education Examination).

Our app, Optional Math Ko Guide, contains the same types of questions with solutions. All of the apps are available for free.
