finite differencing การใช้

• :: Here are some wild ideas : maybe try taking the Lapalce transform of the entire system and see what happens just for fun ? :-) Try to see if an approximation with finite differencing methods is useful.
• For most such methods, warns that " The conditions of stability cannot be determined easily and the time step must be chosen ad hoc . " Another finite differencing method by modifies the formula for the curvature at each vertex by adding to it a small term based on the Laplace operator.
