MAE294B/SIO203B: Methods in Applied Mechanics Winter Quarter 2010 http://maecourses.ucsd.edu/mae294b Homework VI Due February 18, 2010. 1 Calculate the asymptotic expansion of the function E 1 ( x ) = Z x e - t t d t for large positive x using integration by parts. Do the same using Watson’s lemma. 2 Compute two terms in the expansion of the integral Z 0 d x ( ε + x )( 1 + ε x ) for small positive ε . Compare with the exact solution.
