Unformatted text preview: Math 306 – Test 1 Printed Name: Please carefully work all of the following problem(s). You must SHOW YOUR WORK to receive ANY credit! The Printed Name question is worth 5 points. • H indicates a “By Hand” problem where technology is not allowed. • T indicates a “Technology” problem where you a58a58a58a58 may use Mathematica or a calculator. You must still show the steps taken. For example, integraldisplay 5 1 (1- x ) 7 dx =- 8 , 192 is valid. Giving the answer- 8 , 192 without the integral is not. • Do not use DSolve or NDSolve unless otherwise directed (except for checking your work). 1 Find general solutions for differential equations and explicit solutions for initial value problems.
