The difference equation only takes Math III, Math I, Math II and Math IV.

Mainly master the first-order constant coefficient linear difference equation: including the first-order constant coefficient homogeneous linear difference equation and the first-order constant coefficient non-quadratic linear difference equation.

The general solution of the first-order linear equation with constant coefficients is relatively simple,

It is mainly the solution of the first order non-quadratic difference equation with constant coefficients, and it is necessary to know the setting of the special solution form of the non-homogeneous difference equation.

I wish you a happy study.
