Bn are the Bernoulli numbers: https://en.wikipedia.org/wiki/Bernoulli_number

WikiPedia is the first point to start a search for mathemtical questions: https://en.wikipedia.org/wiki/Trigonometric_function#Power_series_expansion . Here you find a hint to Bn also.

Thankyou again Jan. I have found that MATLAB already has the bernoulli numbers stored we just need to access them depending upon the indice i-e bernoulli(2) or bernoulli(4) etc.

Thanks you are always helpful

Hi @Haseeb Hashim

If we are looking at the same source, then you should be able to view this:

Thanks, After some research I understood these numbers. MATLAB also have these numbers in an array called bernoulli we can access from these

Thanks for helping man

Don't mention it, @Haseeb Hashim. More importantly, you have learned something today. A small achievement to move forward!
