Abstract
Eclipsing binary V448 Cyg has a complex light curves and has been repeatedly analyzed by many others. In this paper, new photometric data were used from the TESS project catalogue. Radial velocity and light curves analyze by using PHOEBE program simultaneously show that, there are two models solution. The first model is semi-detach system and has two spots that put one on the primary star and the second one on the secondary star. In the second model, this system is contact and has only one hot spot on the primary star. Finally, the result of these two models are reviewed and compared with previous models.
