Write down the first four terms of the Taylor series expansion of the function x(t-h) about x(t), and the first three terms of the expansion of the function (t-h) dt about x(t). Use these two equations to eliminate d²x (1) (1) and d' d³x (1) dt³ dt² from the Taylor series expansion of the function x(t + h) about x(t). Show that the resulting formula is Xn+1 = -4X₁ + 5X-1 + h(4F + 2F-1) + O(h*) Show that this method is a linear combination of the second-order Adams-Bashforth method and the central difference method (that is, the scheme based on (2.9)). What do you think, in view of this, might be its disadvantages?
