The wavefunction solutions of the above can be solved byusing the WKB method by considering only odd parity solutions of the alternative potential <math>V(x) = mg|x|</math>. The classical turning points are identified <math display="inline">x_1 = - {E \over mg} </math> and <math display="inline">x_2 = {E \over mg} </math>. Thus applying the quantization condition obtained in WKB:
