Can you solve nonlinear differential equations?
Nonlinear differential equations are usually analyzed rather than solved and if they are solved, it is usually by numerical methods rather than explicitly.
What is a nonlinear difference equation?
A nonlinear difference equation is any equation of the form. x-+ =f(x,,, xn-1.), (2) where x„ is the value of x in generation n and where the recursion function f depends on nonlinear combinations of its arguments (f may involve quadratics, exponentials, reciprocals, or powers of the x„’s, and so forth).

How many methods help us solve differential equations?
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices.
How do you solve nonlinear equations numerically?
Any nonlinear equation f (x) = 0 can be expressed as x = g(x). If x0 constitutes the arbitrary starting point for the method, it will be seen that the solution x∗ for this equation, x∗ = g(x∗), can be reached by the numerical sequence: xn+1 = g(xn) n = 0,1,2,…
What do you mean by exact and non exact differential equation?
A first-order differential equation (of one variable) is called exact, or an exact differential, if it is the result of a simple differentiation. Sometimes if an equation is not exact, it can be made exact by multiplying each term by a suitable function called an integrating factor.
