Question: How to input calculated coefficients to corresponding terms in a summation

I have calculated coefficients in maple using a "for...end do" command. For example,

for n from 0 to 1 do A[n] = int(((2*n+1)*(1/2))*simplify(LegendreP(n, cos(theta)))*sin(theta), theta = 0 .. (1/2)*Pi) end do;

A[0] = 1/2

A[1] = 3/4


Here, I can calculate as many coefficients as I want. But, how do I use these coefficients in the following line? For example, I need to calculate a summation. But for each term in the summation, I want to input the coefficients above to the corresponding term in the sum. So. the following summation


will automaticlly attach the numerical values of the coefficients calculated above to the corresponding term in the sum.


I hope this makes sense.
