A New Approach on the Two-Dimensional Differential Transform

In recent years, new formulas of the two-dimensional differential transform have been proven by using definition transform. this work, we use a approach based on and summation properties to prove product two functions, then used result establish other useful formulas. This study shows that procedure can be find for many complicated terms. enables us apply method types partial equations. To demonstrate approach, applied dimensional selected equations compared our results with analytical solutions obtained methods
