Very important: when writing the function you need to type it in quotation marks.This is an implicit method: the value y n+1 appears on both sides of the equation, and to actually calculate it, we have to solve an equation which will usually be nonlinear. One possible method for solving this equation is Newton's method. We can use the Euler rule to get a fairly good estimate for the solution, which can be used as the initial guess of Newton's method.
