Partial differential equation - Wikipedia
https://en.wikipedia.org/wiki/Partial_differential_equationIn mathematics, a partial differential equation (PDE) is an equation which imposes relations between the various partial derivatives of a multivariable function. The function is often thought of as an "unknown" to be solved for, similarly to how x is thought of as an unknown number to be solved for in an algebraic equation like x − 3x + 2 = 0. However, it is usually impossible to write down explicit formu…

The section also places the scope of studies in APM346 within the vast universe of mathematics. A partial di erential equation (PDE) is an gather involving partial derivatives. This is not so informative so let’s break it down a bit. 1.1.1 What is a di erential ...
