*Fr.: équation différentielle exacte*
A → *differential equation* composed of
→ *continuous*
→ *differentiable function*s for which certain conditions
are fulfilled. The equation *M(x,y)dx + N(x,y)dy* = 0 is called exact if
*M(x,y)* and *N(x,y)* are continuous differentiable functions
for which the following relationship is fulfilled:
*∂M/∂y = ∂N/∂x*, and *∂M/∂y*
and *∂N/∂x* are continuous in some region. → *exact*; → *differential*;
→ *equation*. |
