The integration strategies use 'integration rules' that compute integral estimates using weighted sums.Drawn from the in-product documentation of Mathematica, the 23-title Tutorial Collection gives users targeted instruction on the functions, capabilities, and unified architecture of the Mathematica system....
So, I set out and tested this in Mathematica and Julia: I define a mockupUin(t), pass some parameter values, and then build an array ofUout(t), at timet = 0, for a range offref. Julia:I used theQuadGKpackage for numerical integration. T=0.1f=100.Uin(t)=sin(2pi*f*t)+sin(...

A suggestion is to replace the infinite sum with an upper limit of ~50 as it converges quickly. This does allow Mathematica to now evaluate the integral.numerical-integration summation astronomyShare Improve this question Follow edited Jun 27, 2014 at 16:17 asked Jun 27, 2014 at 11:56 ...
