It is similar to the (standard) Euler method, but differs in that it is an implicit method. The backward Euler method has error of order one in time.

These implicit methods require more work per step, but the stability region is larger.

A linearized implicit Euler method is used for the temporal discretization of the gridless type solver with the following linearizing assumption. 2020-01-15
In numerical analysis and scientific computing, the backward Euler method (or implicit Euler method) is one of the most basic numerical methods for the solution of ordinary differential equations. It is similar to the (standard) Euler method , but differs in that it is an implicit method . These videos were created to accompany a university course, Numerical Methods for Engineers, taught Spring 2013. The text used in the course was "Numerical M
while one is treated explicitly and the other implicitly. For usual applications the implicit term is chosen to be linear while the explicit term can be nonlinear. This combination of the former method is called Implicit-Explicit Method (short IMEX,).

However, because of this, at each time-step, a multidimensional nonlinear equation must be solved. Eq. (16.78) discretized by means of the backward Euler method writes Implicit Euler Method System of ODE with initial valuesSubscribe to my channel:https://www.youtube.com/c/ScreenedInstructor?sub_confirmation=1Workbooks that An implicit method, by definition, contains the future value (i+1 term) on both sides of the equation. Consequently, more work is required to solve this equation. Since the c_e(i+1) shows up on both sides, you might try an itterative solution, such as make an initial guess, then use Newton-Raphson to refine the guess until it converges.
