sum of trigonometric series formula We can use the sum to product formulas to rewrite sum or difference of sines cosines or products sine and cosine as products of sines and cosines See Example
How can we sum up sin and cos series when the angles are in arithmetic progression For example here is the sum of cos series sum k 0 n 1 cos a k cdot d frac sin n times frac d 2 sin frac d 2 times To sum the series sin a sin a b sin a 2 b sin a n 1 b S displaystyle sin a sin a b sin a 2b cdots sin a n 1 b S Multiply
