In this paper, the symmetries and Lie algebra of a coupled nonlinear wave equation were discussed. One-parameter transformation groups of this equation were obtained by using the symmetries.
The Schrodinger equationof time - dependent harmonic oscillator is solved by the time space transformation, and its application in physics is presented.
