Unformatted text preview: Math 306 Test 1 Chapter 1 Printed Name: H indicates a By Hand problem where technology is not allowed. 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 ....
