Revision Notes
... In an equation letters stand for missing numbers. To solve an equation is to find the missing value of the letters. To keep balance we will do the same operation to both sides of the equation, the left hand side and the right hand side. To solve the equation 2x + 7 = 19 we need to find an x value wh ...

12.1 Systems of Linear equations: Substitution and Elimination
... If the lines are identical, then there are infinitely many solutions. Each point on the line is a solution. The system is consistent dependent. If the lines are parallel, there is no solution. The system is inconsistent. System of equations can be solved graphically (you need a very accurate graph f ...

Partial differential equation
In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. (A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.) PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model.PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
