Volterra integral equations are particular importance in various branches of science. The subject of the presented paper is applying the Laguerre polynomials method and collocation method for solving linear Volterra integral equations. For this purpose, we approximate the unknown function by Laguerre series expansion and then we use collocation method on integral equations and we change integral equations into their matrix forms. Next coefficients unknown function is obtained with necessary calculations. One of advantages of this method is that there is no need to solve the system.
