This great book explicitly presents the numerical solution of general third order ordinary differential equations using both block method and Taylor series as predictors. Hybrid continuous Linear multi step methods were developed in an easy to know version. The author painstakingly demonstrated the appropriate use of hybrid block method and Taylor series as predictors for the solution of third order ordinary differential equations. These methods are more accurate and efficient than those of existing authors. The basic properties of the methods were well examined. Engineers, scientists and technicians will find it very useful in solving third order ordinary differential equations that are common in the field of science and engineering . It is a must read by every student, teacher and lover of mathematics (numerical analysis)!
