I am not sure this is something that is possible to implement in mathematica, but my question is the following.
I have a system three linear equation where the coefficients in front of each variable is a sum. The equations have the following expression (I am just reporting one of them)
Sum[y_i/(s_i)^2] - Kx *Sum[Sin[p_i]/(s_i)^2] -Ky *Sum[Cos[p_i]/(s_i)^2] -G *Sum[1/(s_i)^2]
The variable I need to find are Kx, Ky, G and I know all the y_i, p_i, s_i. I know how to obtain the numerical solution for the variable I am looking for, but I was wondering if it is possible also to find an analytical one. I was thinking to use
Array[y, 13]
but then i don't know how to do the sum of the different element.
Someone can help me?
