\) The coefficients are chosen to match the computed values of the solution y n and p n 1, from predictor stage. The simplest case uses a first degree polynomial \( P_1 (t) =at b. Gear is well-known for his contributions in numerical analysis and computer science. William Gear (born in 1935, London, UK) on so called stiff differential equations, whose solutions are very difficult to approximate by discussed so far methods. These methods became widely used in the 1970s because of the work of C. These algorithms are called backward differentiation formulas. More precisely, a method is called a multistep k-step method if the computation of the next approximate solution y n 1 is based on the last approximate solutions \( y_n, y_ \right) \) to obtain an implicit formula for y n 1. methods that use information at more than the last mesh point are referred to as miltistep methods. After several points have been found, it is feasible to use several prior points in the calculation. The methods of Euler, Heun, Runge-Kutta, and Taylor are called single-step methods (or one-step methods) because they use only the information from one previous point to compute the successive point that is, only the initial point (x 0, y 0 ) is used to compute (x 1, y 1 ) and, in general, y k is needed to compute y k 1.
