MAE 294A / SIO 203A – Introduction to Applied Mathematics I – Fall 2009 Homework # 3 Assigned: October 15 2009 Due: October 22 2009, in class. 1. (5 points) Solve the following eigenvalue problem on the domain [0 ,L ] y 00 + Ey = 0 , y (0) = 0 , y 0 ( L ) + y ( L ) = 0 . 3. (4 points) Classify all the singular points (ﬁnite and inﬁnite) for the spheroidal wave equation (1 - x 2 ) y 00 - 2 xy 0 + λ + 4 θ (1 - x 2 ) - μ 2 1 - x 2 ! y = 0 , for all values of the parameters λ , θ , and μ . 4. (5 points) Obtain the series solution to the initial value problem y 0 + y = e - x , y (0) = 1 . By comparing this with the direct solution of the diﬀerential equation, show that
