The solution is obtained through two new formulas obtained through the modification of the exponential shift theorem and using differentiation techniques and the properties of linearity. Next, two examples are given to provide a deeper understanding of the use of the obtained formulas. The solution for both examples using this technique is the same as those obtained using the undetermined coefficient method.enNonhomogenous ordinary differential equationundetermined coefficient methodderivativescomplex exponential functionsArticle
