Setting in , and letting , we find that These conclusions agree with the case , for which it is easy to show that the solution is . 15 . See Prob. . It follows that the solution of the IVP is . This function is a multiple of the answer in Prob. . The maximum value is calculated as that the appropriate value of is . Based on Prob. . Hence the peak value occurs at We find . , the solution is . Since this function is a multiple of the solution in Prob. with The solution attains a value of that is, . . Similar to Prob. , for , we have , for , , , the solution is , in which It follows that . Setting in Requiring that the peak value remains at . These conclusions agree with the case that the solution is , and letting , we find that , the limiting value of is , for which it is easy to show . 16 .
