Implicit and explicit differential equations

Witryna19 wrz 2016 · We can differentiate either the implicit or explicit presentations. Differentiating implicitly (leaving the functions implicit) we get. 2x +2y dy dx = 0 so dy … Witryna14 mar 2016 · Suppose we go from the equation and go backwards: y = c e x + e 2 x + c. where c is any arbitrary constant. Now, y ′ = c × ( e x) + ( 2 e c) × ( e 2 x). Solving for c: we get. c = ln ( y ′ − y e 2 x). Putting the value of c in original equation we get the differential equation as: 2 y = ln ( y ′ − y e 2 x) × ( e x) + y ′.

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. saai south africa
