Dear All Mathematica user Im trying to use Mathematica for Summation of Trigonometry expression..... but it can't be evaluated as I think the expression is too BIG or LONG. I think it must be simplified further before evaluated in mathematica. Kindly give me your opinion. please The summation has to be done for the below expression from n=1 to n=126 expression1=> A.cos(w+ i.delta)t from i=1,2,3... to i=N=126 A is amplitude, w angular frequency, delta is just a spacing/interval, t is time of course. This is a typical sinusoidal signal. But to find the summation for all the terms from i=1 to i=126, I need to have maybe a simplified power series to be evaluated in mathematica? or ? I dont know, as mathematica cant find the answers. Kindly help me . Thank you so much in advance Wish to hear from you all rgds and thanks Jason
