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
