4 a Consider the initial value problem begin aligned y prime x 1 y x text for x in 1 1 y 0 0 end aligned Verify that y x 1 exp x is a solution Show that Picard s theorem applies to this problem with f 1 1 x 1 e 1 1 e R Can you find any more solutions to this initial value problem If so find one or more otherwise explain why not
