SIMULTANEOUS DIFFERENTIAL EQUATIONS Example 1: So far we have intentionally considered rather simple aystems. Ia more complex systems we must deal with simultaneous differential equations in several variables Such equations can be solved directly, as in the stato-variable approach discussed in Chapter s, or by eliminating variables to obtain differential equations in a single variable only, as shown in the following discussion. 2 H 1 H 2Ω Fig. 1.18 Consider the electrical network in Fig. 1.18. The loop equations are (2D + 5)n (1)-Syn(t) = f(t) SIMULTANEOUS DIFFERENTIAL EQUATIONS Example 1: So far we have intentionally considered rather simple aystems.
