Implicit and explicit differential equations
Explicit and implicit methods are approaches used in numerical analysis for obtaining numerical approximations to the solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. Explicit methods calculate the state of a system at a later time from the state of the system at the current time, while implicit methods find a solution by solving an equation involving both the current state of the system and the later one… WitrynaThis video goes over implicit solutions of differentia... This video introduces the basic concepts associated with solutions of ordinary differential equations.

WitrynaAn implicit function is a function, written in terms of both dependent and independent variables, like y-3x 2 +2x+5 = 0. Whereas an explicit function is a function which is represented in terms of an independent variable. For example, y = 3x+1 is explicit where y is a dependent variable and is dependent on the independent variable x.
