With the help of this method, we use backward space difference provided that the wave speed c is positive and if c is negative, we have to ensure the stability by using forward difference
The discrete-time analogue of the Lie derivative of a function ([phi](x) is its difference, which can be defined in two different ways, either as the forward difference
omega]] f(t) = f (t + [omega]) - f(t) / [omega] is the forward difference
operator with stepsize [omega] , and [D.
0]), and [DELTA] denotes the forward difference
operator, that is, [DELTA]x(n) = x(n +1) - x(n) for a sequence x(n).
where [DELTA] is the forward difference
operator defined by [[DELTA][mu].
The non-linear first order differential equations under study are replaced by finite forward difference
It can be easily seen that the polynomial enclosed in the first square brackets fits the curve y(x) satisfying the given data, which is the Newton's forward difference
In this section, we give a theorem which provides some estimates on these type of the inequality (2) about the forward difference
dX have been expressed by forward difference
Cuadratic Function Forward Difference
M1 M2 M3 error 0.
We are using here forward difference
It is really pathetic to forward differences
of opinion from dialogue to court," said ANHRI.
