Abstract :In this paper, we formulate Maclaurin coefficients of a function, not necessarily analytic at point $0$, by using Laplace transform as follows: $$ f^{\left(n\right)}\left(0\right)=\frac{1}{\left(n+1\right)!}\lim_{r\to+0}\frac{d^{n+1}}{dr^{n+1}}L\left\{f\right\}\left(\frac{1}{r}\right), $$ where $L$ is the Laplace transform, $r=\frac{1}{s}$, $s$ is the variable of the Laplace transform and $n\in\mathbb{N}\cup\left\{0\right\}$. Also, we apply this formula on some functions. Finally, we give new formulas for Bernoulli numbers via Polygamma function and Hurwitz zeta function.Keywords : Maclaurin coefficients, Laplace transform, Bernoulli numbers, Polygamma function, Hurwitz zeta function
