Abstract

In this research work, two and three step second derivative hybrid block backward differentiation formulae (SDHBBDF) method of order 6 and 7 are presented for the numerical solution of stiff initial value problems. The block scheme was obtained through increasing the number k in the multi-step collocation (MC) with the aid of maple software. The stability analysis of the method have shown that the schemes are A-stable and consistent. We compared SDHBBDF methods with exact solutions and have shown that the results obtained using proposed new block methods are excellent for the solution of stiff problems.
