First Exercise

Problem 1.2-2
  Find a function y=f(x) which satisfies the 
   differential equation dy/dx = (x-2)^2 
   and the initial condition y(2)=1.
 Book's Answer: y=1+(1/3)(x-2)^3
 Your Job
    Please write a one or two page solution.
    Submit a COPY on the 3rd day of class.
    The final draft of 1.2-2 will be collected with 
    Week 1 homework in a stapled package (due in Week 2).
 Sample Solved Problem
    The link below is handwritten work by Gustafson, Tyson Black and Jennifer Lahti. Try to do 
    as well as Jennifer (best exposition in this PDF), but write your own draft, using your own style. 
    Tyson's work for 1.2-1 shows the range of what is acceptable. 

    This is practise writing mathematics, with the mysteries removed. Does playing music qualify you to
    write musical notes? If you agree that listening to the radio has nothing to do with reading and writing
    musical notes, then you are beginning to understand the difference between writing mathematics and
    being a mathematical consumer. Engineers are not just consumers of mathematical methods, they are authors 
    of new methods, which is a nontrivial creative effort requiring special writing skills. Knowing how to
    write mathematics enables you to read modern engineering publications, which always seem to have new 
    technological and mathematical content.
