Presents new vector matrix form formulas for solving linear time invariant state equations. The responses of linear continuous and discrete systems may be decomposed into force responses and free responses. The force responses are discussed in detail. For first order circuits the new formula is similar to ordinary three element formula. The new three element formula is suitable for solving state equations of which the exciting functions are constants, exponential functions, or sinusoidal functions etc. Some formulas are given for solving the above state equations. The new formula can be used to solve state equations to distinguish stable and free responses.
