Equations that have more than one unknown can have an infinite number of solutions that make it true. For example, \(2x + y = 10\) could be solved by: \(x = 1\) and \(y = 8\) \(x = 2\) and \(y = 6\) \ ...

The unknown values in an equation could be the individual costs of a smoothie and a banana when the combined cost is known. Simultaneous equations can be useful when running a business. Watch the ...

The Annals of Probability, Vol. 34, No. 2 (Mar., 2006), pp. 663-727 (65 pages) We develop a new method to uniquely solve a large class of heat equations, so-called Kolmogorov equations in infinitely ...
