Continuous dynamic systems 47 Figure 2.10. But equation (2.18) is just a particular example of a more general differential equation dx dt = g ( t ) f ( x ) (2.19) Any differential equation which can be written in terms of two distinct functions f ( x ) and g ( t ) is said to be a separable differential equation. Some examples are the following: (i) dx dt = 1 x 2 (ii) dx dt = x (2 x ) (iii) dx dt = ± 1 2 xt Our interest in these particular differential equations is because they are often

Unformatted text preview: possible to solve fairly readily since we can write one side in terms of x and the other in terms of t . Thus, writing (2.19) in the form f ( x ) dx dt = g ( t ) we can then integrate both sides with respect to t f ( x ) dx dt dt = g ( t ) dt + c or F [ x ( t )] = g ( t ) dt + c...
