This paper shows how to use the method of quasisolutions to construct exact solutions to Burgers’ equation. A function υ=υ ( x, y ) is called a quasisolution of a PDE in case there exists a function φ (not a constant function) of one variable so that u ( x, y )= φ ( υ ( x, y )) is a solution of the equation. We prove a theorem giving necessary and sufficient conditions for υ to be a quasisolution to Burgers’ equation. A function φ can then be found explicitly so that u=φ ( υ ) is an actual solution. Combining this technique with similarity methods, we find a continuum of solutions to Burgers' equation.
