Query: Shifted Chebyshev polynomials for Solving Three-Dimensional Volterra
  Integral Equations of the second kind   In this paper, an efficient method is presented for solving three dimensional
Volterra integral equations of the second kind with continuous kernel. Shifted
Chebyshev polynomial is applied to approximate a solution for these integral
equations. This method transforms the integral equation to algebraic equations
with unknown Chebyshev coefficients. Numerical results are calculated and the
estimated error in each example is computed using Maple 17.
