We provide numerical solution to the one-dimensional wave equations in polar coordinates, based on the cubic B-spline quasiinterpolation.\r\nThe numerical scheme is obtained by using the derivative of the quasi-interpolation to approximate the spatial\r\nderivative of the dependent variable and a forward difference to approximate the time derivative of the dependent variable. The\r\naccuracy of the proposed method is demonstrated by three test problems. The results of numerical experiments are compared with\r\nanalytical solutions by calculating errors ??2-norm and ??8-norm.The numerical results are found to be in good agreement with\r\nthe exact solutions.The advantage of the resulting scheme is that the algorithm is very simple so it is very easy to implement
