<p>The aim of this paper is to introduce two new extensions of the Jacobi and Laguerre<br>
polynomials as the eigenfunctions of two non-classical Sturm-Liouville problems. We<br>
prove some important properties of these operators such as: These sets of functions are<br>
orthogonal with respect to a positive de nite inner product de ned over the compact<br>
intervals [-1, 1] and [0,1), respectively and also these sequences form two new orthog-<br>
onal bases for the corresponding Hilbert spaces. Finally, the spectral and Rayleigh-Ritz<br>
methods are carry out using these basis functions to solve some examples. Our nu-<br>
merical results are compared with other existing results to con rm the eciency and<br>
accuracy of our method.</p>
