Q: How to get from discrete Fourier transform formulas to the continuous ones?

Ryder RudeI read on the internet about how discrete Fourier transform works. Based on that, I made up these formulas. A discrete function $g(t)$ takes $N$ values at equally spaced intervals between $t=a$ and $t=b$. $g(a)=g(b)$. Now, the values of the function at $a, a+\frac{b-a}{N}, a+\frac{2(b-a)}{N},.......
