Expansion of COS N Theta and SIN N Theta in terms of cosines and sines of multiple of theta by using noor's triangle

In the present study we introduced a triangle, like Pascal's triangle, to obtain directly the coefficients in the expansion of θ n cos and θ sin in terms of cosines and sines of multiple of θ , where n is any positive integer. This type of expansion is given by Datta et al. in which they ha...
