Suppose we are trying to use the existence and uniqueness theorem from section 2.1 on the following rst order initial value problem: {'91 : ay) 9(3)=7 where it is known that f and all of its partial derivatives exist and are continuous, except at the points {0,0} and (5,10). What is the area of the largest rectangle R we can select, satisfying the hvpotheses of the existence and uniqueness proof
