One exception is the Apart command which may be used at any time. • T indicates a “Technology” problem where you :::: may use Mathematica or a calculator. You must still show the steps taken. For example, Z 5 1 (1- x ) 7 dx =- 8 , 192 is valid. Giving the answer- 8 , 192 without the integral is not. Please put your name on computer work as well as the problem number! • Do not use DSolve or NDSolve unless otherwise directed (except for checking your work). Grade of 110 1 Solve the following ODEs. H A 10 pts y + y = 1 1 + e 2 x . ............................................................................................................................ H B 10 pts xy = y + 2 xe- y/x . H 2 10 pts Find the value of n for which the equation ( xy 2 + nx 2 y ) dx + ( x 3 + x 2 y + 1) dy = 0 is exact. Then solve the equation using that value of n ....
