tlist = Table[i, {i, 1, 10}]
tlist:{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
f = E^(-((2 t)/T));
Sum[f, {t, {tlist[[i]], {i, 1, 8}}}]
How to calculate Sum of a function over a list?
One way to do this is by defining f[t_]:= E^(-((2 t)/T));
Is there a way to do it in any other manner. Because I have to do this for various functions with a higher level of complexity.
