Using singular to solve system of differentiation equation

when solving motion on surface,
there are two differentiation equations with repect to two variables?

How to solve it in singular?

Any books mentioned the procedure to solve them?

Sorry typing error, it is differential

Hard to answer such a vague question.
Do you mean the Langrage equations?

Singular is mainly for computing with algebraic
equations (objects) but not for solving differential equations,

I read a book which last page
using polynomial to solve system of differential equations

Hi, please post here the system you want to solve. Some parts of Singular can be used to solve ordinary/partial differential equations, mostly linear. Though it all depends on your system.

i do not have system of differential equations.
i just want to understand and solve this in my program
