A high convergent precise exact analytic method for differential equation with variable coefficients (Q2368196)

A new high precision algorithm is given based on [\textit{Z. Ji} and \textit{K. Yeh}, Appl. Math. Mech., Engl. Ed. 10, No. 10, 885-896 (1989; Zbl 0742.65064)] for a bending problem of variable cross-section beams. It can have the fourth order convergent precision without increasing computation work.
