(a) Explanation Given: d y d x = y , y ( 0 ) = 1 And, d y d x = y + y x ln x , y ( e ) = 1 Calculation: Consider the given equation. d y d x = y Separate the variables of the above equation. d y y = d x Integrate the above equation. ∫ d y y = ∫ d x ln | y | = x + c Substitute 1 for y and 0 for x in above equation. ln | 1 | = 0 + c c = 0 Hence the solution is, ln | y | = x y = e x [ Exponentiating both sides ] Consider the given equation. d y d x = y + y x ln x Separate the variables of the above equation. d y d x = y ( 1 + 1 x ln x ) d y y = ( 1 + 1 x ln x ) d x Integrate the above equation (b) To determine To show: There are more than 1.65 million digits in the y -coordinate of the point of intersection of the two solution curves.
