The integral form was proven by Richard Bellman in 1943.
The law can be written in two forms, the "integral form" and the "differential form".
Lagrange gave a proof in 1770 based on his general theory of integral quadratic forms.
The formulation is based on integral form of Maxwell equations.
This relation can also be written in integral form.
The conservation laws can be written in integral or differential form.
This can be turned into an equation in integral form over the control volume.
The integral form for the generalized Borel transform follows as well.
A large proportion of English secondary schools no longer have an integral sixth form.
The original formulation was in an integral form slightly different from the above.
