Summary: A study of efficient approximate methods for solving the Cauchy type singular integral equations (CSIEs) of the first kind, over a finite interval, is presented. In the solution, Chebyshev polynomials of the first kind, \(T_n(x)\), second kind, \(U_n(x)\), third kind, \(V_n(x)\), and fourth kind, \(W_n(x)\), corresponding to respective weight functions \(W^{(1)}(x)=(1-x^2)^{-\frac 1 2}, W^{(2)}(x)=(1-x^2)^{\frac 1 2}, W^{(3)}(x)=(1+x)^{\frac 1 2}(1-x)^{-\frac 1 2}\) and \(W^{(4)}(x)=(1+x)^{-\frac 1 2}(1-x)^{\frac 1 2}\), have been used to obtain systems of linear algebraic equations. These systems are solved numerically. It is shown that for a linear force function the method of approximate solution gives an exact solution, and it cannot be generalized to any polynomial of degree \(n\). Numerical results for other force functions are given to illustrate the efficiency and accuracy of the method.
