U(x;y) = F(x) G(y) 13 Conclusion Notice that where the solution of an ODE contains arbitrary constants, the solution to a PDE contains arbitrary functions In the same spirit, while an ODE of order mhas mlinearly independent solutions, a PDE has in nitely many (there are arbitrary functions in the solution!) These are consequences of the(b) Since f and g are integrable on a;b, then f g and f g are integrable Since squares of integrable functions are integrable, then (f g)2 and (f g)2 are integrable Thus, by (a), 4fg is integrable and fg is integrable, as desired Question 5 Consider the function f on 0;1 given by f(x) = ˆ x if x 2Q 0 if x 62Q (a) Let P = f0 = tApr 15, 21 · The GWFA1000RN8AER Royal Navy x GShock Frogman (to give it its typically lengthy full Gshock name) was released on April 7 in the UK for 799 British pounds (around $1,115 US), which is 100
