Partial Differential Equations in Two or More Dimensions

In this equation, (n(x) are the basis functions that can be obtained from Table 7-1 (n(x) = sin(n(x) , n = 1, 2, … Each term in equation (7.1-10) is a product of two functions, each involving only one spatial variable. This feature is similar to the method of separation of variables. ................
