This paper discuss the relation between Taylor's formula and partial differential equation. Taylor formula iteration method can resolve partial differential equation u(x,t) be expanded at t=0 or t=1 by Taylor formula. Coefficient of Taylor formula ut(x,0), utt(x,0). . . can be expressed by partial differential equation. The method can solve nonlinear differential equation. Generalized Taylor's formula can solve fractional partial differential equation. The method is very important way that resolving partial differential equation. This article refers to the literature. Taylor formula iteration method belongs to logical thinking.
