Divide 2, the coefficient of the x term, by 2 to get 1 Then add the square of 1 to both sides of the equation This step makes the left hand side of the equation a perfect square x^ {2}2x1=\frac {y1} {3}1 Square 1 x^ {2}2x1=\frac {y2} {3} Add. Initialvalue problems y y, y(0) x3 and y y, y(1) 2 other than y 3e and y 2ex 1, respectively This follows from the fact that f(x, y) y and f y 1 are continuous throughout the entire xyplane It can be further shown that the interval I on which each solution is defined is (, ).
